Comment: - First sentence: I suggest to stop the sentence after "and the gravitino as the lightest SUSY particle".  The rest is not needed in the abstract, I believe.

Response:

Comments - line 7-8: "in the electron+jets and muon+jets channels that require one or two photons in the final states":
I suggest to replace this with  "in final states containing an electron or a muon, jets, and one or two photons" or similar.

Response:

1. Introduction

Comment - I would suggest to add a (feyman-like) diagram of the simplified model that you are targeting.

Response:

Comment - l.2 : "theoretical option for avoiding" --> "extension of the Standard Model that avoids"

Response:

Comment - l.3:  "hierarchy problem evident from the recent discovery" --> I'm not sure that the recent discovery of the Higgs made the hierarchy problem evident.
What about "hierarchy problem, which became particularly relevant since the recent discovery" or similar.

Response:

Comment - l.6-8: I would remove this sentence ("Since such … LHC."). It's confusing and not needed.

Response:

Comment - l.9: I would remove "based on events with pairs of photons" since you discuss the final state later.

Response:

Comment - l.10: "in data corresponding" --> "in a dataset corresponding"

Response:

Comment - l.15: remove "leading to photons in the final state." (it's obvious from the rest of the sentence)

Response:

Comment - l. 16: check spelling of "R-parity" (with or without hyphen)

Response:

Comment - l. 16-18: I would remove the sentence "Assuming R-parity … at the LHC". It's not needed here.
I would directly say "In this analysis we focus on pair production of top squarks, where each top squark decays to a top quark and a neutralino, which in turns decays to a photon and a neutralino."

Response:

Comment - l. 23-26: I don't understand this sentence. What about
"The analysis concentrates on the semileptonic decay of the ttbar pair and therefore requires the presence of ..." and stopping the sentence after "gamma+jet backgrounds." (on l. 25).

Response:

Comment - l. 30: is "false photons" really an appropriate name?

Response:

Comment - l. 32-35:  I would not discuss the freely floating normalisation of ttj and ttgamma in the introduction (I only understood on l. 227 what you exactly mean). So I would remove the sentence on l. 32-35 "To reduce …. in pTmiss.".

Response:

2. The CMS detector

fine.

3. Event and object reconstruction

Comment - l. 58: "Objects in the event" --> "All physics objects ..."

Response:

Comment - l. 59: "PF-particles candidates" --> I would suggest either "PF candidates" or "PF particles" (on l.64 you use "candidates")

Response:

Comment - l. 84: is the isolation cone for muons really 0.4? (not 0.3 for electrons) Why? Can you double check?

Response:

Comment - l. 88: I would remove "thereby increasing sensitivity to signal", since you are just talking about objects here.

Response:

- l. 91: remove "for tagging" in this sentence.

Response:

4. Analysis strategy

- l. 93-95: you mention the trigger thresholds here, but you do not discuss the trigger efficiency (100% I guess, but you should say that).
Also, since this is the section where you outline the analysis strategy, it's worth to repeat that the offline cuts on electrons and muons are 30 GeV.

Response:

- l. 114-115: "jet component of the lepton + jets ttbar decays" --> what about "jets from the top decays"?

Response:

Comment: - l. 117: "many selected photons"? What about saying "where selected photons may originate from"

Response:

Comment- l. 118 and l. 125: "lowest-order" --> "leading order"

Response:

Comment- l. 129: shouldn't you mention that GEANT was used for the detector simulation?

Response:

Comment- l. 130: "correspond to small backgrounds" --> "represent small backgrounds"

Response:

Comment- Table 1: in the last sentence of the caption you mention "fluctuating the template distributions by the syst uncert."
It isn't clear what you mean here. I suggest to explain this in the text and shorten the caption.

Response:

Comments- Figure 1: these plots are used to determine the SF … but the ratios seem to be very close to 1 in the Z-region. Are the SF's already applied here?
Can you clarify?

Response:

Comments- l. 158: "component" --> "ingredient"?

Response:

Comments - l .170-173: unclear what you mean here. It only gets clear at l. 226. So I suggest to shorten or remove this sentence.

Response:

Comments- l. 174: "provide an evaluation of the performance of the prediction" --> maybe "allow us to validate the prediction"?

Response:

Comments- l. 181-182: unclear what you mean with "(1-d/b) percent uncertainty" … do you mean "fractional uncertainty"? Please rephrase.

Response:

Comment - l. 182-185 and Fig. 2 (bottom): since you don't use CR2, I suggest you drop the plot of CR2 (fig. 2 bottom) and just argue that due to the limited
number of events in CR2, you decided to use an alternative method to determine the uncertainty on SR2.

Response:

Comment- l. 187-188: please rephrase "signal region simulation of the distributions in ptmiss in the control region"

Response:

Comment - l. 189 and 190: "difference"… difference in what? I assume in pTmiss shape?

Response:

Comment- l. 192: which distributions? … pTmiss?

Response:

5. Results and interpretation

Comment- l. 194: fix latex label

Response:

Comment- l. 198: "normalizations of cross sections affected by choices in PDF and factorization and normalization scales …
" --> I would just say by "by PDF and scale uncertainties"

Response:

Comment- l. 201: "obtained from" --> "derived from"?

Response:

Comment - l. 202: the citations are partially missing here

Response:

Comment - l. 209: I would suggest to change "m_ {top squark}" in to "m_{\tilde t}"

Response:

Comment - Table 2: caption: typo in "uncertainties"

Response:

Comment - l. 214: "to force the strong production" --> "so that the only relevant process is the production of ..."

Response:

Comment- l. 225: "taken as syst. uncert. for both their upwards and downwards fluctuations" : please rephrase

Response:

Comment- l. 226 - 228: "single +- 100% nuisance parameter":  please rephrase this sentence in proper english.

Response:

Comment - l. 231: I would prefer that you quote the precise mass limits (corresponding to the highest and lowest LSP mass)

Response:

Comment - l. 231: "mass-exclusion contours" -->
"exclusion contours"

Response:

Comment - Figure 4 caption: say "observed (top) and expected (bottom) upper limits"

Response:

6 Summary

Comment - l. 236: "distribution in" --> "distribution of"

Response:

Comment - l. 238: be specific about which LSP mass these numbers correspond to

Response:

Comment - l. 240: drop this last sentence

Introduction. Are there other relevant searches that you should be citing?

Response: Waiting on Brian to give me a set of references.

Comment -line 16. I don't understand the connection between R parity and strong production. Maybe just drop the "Assuming that R parity is conserved" clause?

Response: The R parity connection is with "pair production", not strong interaction.

Comment: -line 32-35 This sentence is not so clear to me. Perhaps restructure it to say the following. "The normalization of the XXXXXXX background(s) are allowed to float freely in the fit, which helps avoid uncertainty in the tt+jets, tt+gamma, and tt+gamma,gamma production cross sections."

Response: The sentence in question has been restructured. Response 2: You had better check this modified sentence Brian.

Comment -line 58. There's something wrong in the parenthetical list. muons and photons at least should be there, I guess.

Response: Done

Comment -line 66. Should add a reference to something for the photon ID.

Response: Reference 27 for photon reconstruction and ID is a line or two later in the text

Comment -lines 93-95 on the trigger would fit better at the beginning of Sec. 3.

Response: We tried positioning 93-95 st the beginning of section 3 but it fit better in our estimation in section 4 which has been relabeled as Event selection and analysis.

Comment -lines 96-99. Say explicitly that one lepton is required here.

Response:

Comment -lines 96-99. I'd move the sentence about the extra lepton veto to the end of this paragraph.

Response:

Comment -lines 116-129. You should mention GEANT used for the simulation somewhere.

Response:

Comment -line 152. I don't understand "data MC sample." Is it maybe just a typo and should be "data sample?"

Response:

Comment -line 182. Is there a reference for the Kolmogorov-Smirnov test?

Response:

Comment -line 194. Fix the latex here.

Comment -line 205-206. The sentence with the reference to Table 2 should go at the end of the previous paragraph, i.e. at line 202.

Response:

Comment -line 210. I guess "100% bino-like" is meant to signify that the decay is 100% to photon,gravitino. It would be better to also say that explicitly.

Response:

Comment -line 207-216. Give the gravitino mass, too. As it's written now, it looks like it would be decoupled, which certainly isn't what you mean.

Response: Brian, what was the gravitino mass? 1 KeV??

Comment -line 207-216. Mention FastSim, if you are using it (or GEANT if you are not).

Response:

-line 221 "that are integrated over in the analysis" I don't understand this clause.

Response:

type A

Comment -abstract line 3 rewrite as "...with a bono-like neutralino as the next-to-lightest SUSY particle." There is more than one neutralino, so writing "the neutralino" doesn't seem right to me.

Response:

Comment -line 2 remove "is considered to be"

Response:

Comment -line 8 "still remain to be pursued" => "are worth pursuing"

Response:

Comment -line 25 drop ", and an enhanced leptons+jets mode in tt decays." Or else rewrite that to make it more clear what the point is. I don't get what you mean as it is written now.

Response:

Comment -line 30. "false photons" is a strange construction to me. I'd prefer "fake photons," but I'm guessing someone else has already asked to you to change from that. I leave this one up to you at this point.

Response:

Comment -line 59. "PF-particles" => "PF-particle"

Response:

Comment -line 103 "photon candidates" => "photon candidate"

Response:

Comment -line 118. I've never seen LO written as "lowest-order." I think "leading-order" is more common.

Title: Search for natural supersymmetry in events with top quark pairs and photos in pp collisions at sqrt s = 8 TeV

Fine!

Comment: Abstract

Results are presented from a search for natural gauge-mediated supersymmetry in a scenario in which the top squark is the lightest squark, the next-to-lightest SUSY particle is a bino-like neutralino, and the lightest SUSY particle is the gravitino. The strong production of top squark pairs can produce events with pairs of top quarks and neutralinos, with each neutralino decaying into a photon and a gravitino. The search is performed using a sample of pp collision data accumulated by the CMS experiment at sqrt s = 8 TeV, corresponding to an integrated luminosity of 19.7 fb^{-1}. The final state consists of a lepton (an electron or muon), jets, and one or two photons. The imbalance in the transverse momentum in the events is compared with expected spectrum from standard model processes. No excess event yield is observed above the expected background, and the result is interpreted in the context of a general model of gauge-mediated SUSY breaking, leading to the exclusion of top squark masses below 650â€”750 GeV.

-In the original version, the phrase â€œgravitino as the lightest SUSY particle with a bino-like mixing of the neutralino, the next-to-lightest SUSY particle,â€ seems hard to read.

- In the original version, a comma is definitely needed after â€œ19.7 fb^{-1}â€ . Otherwise, the sentence implies that this lumi applies channel by channel. Having both the data sample and the signature in a single sentence seems like too much.

- In the original version, the phrase â€œgauge-mediated SUSY breaking that leads to the exclusionâ€ is grammatically fine, but I think it isnâ€™t quite the meaning that you want. I think there should be a looser connection between the model and the result.

Response: The wording of the abstract is changed as suggested.

1. Introduction

Comment: L6 ***Suggest changing â€œand the lightest Higgsino [â€¦]â€ to â€œand the Higgsinos [â€¦]â€

As far as I know (e.g., Papucci et al.) all four Higgsinos are expected to be light in natural SUSY. In fact, in the limit that they are pure Higgsino, they are mass degenerate.

Response: Done

Comment: L6-L8 ***I am not sure that I am following the logic of this sentence. It seems to say start with a theoretical motivation and the says that this indicates that there are many searches left to be done at the LHC. To me these are two separately true statements, but the first one does not imply the second one. Also, why are you referring to the little hierarchy problem here, whereas previously you referred to the hierarchy problem?

Here is a suggestion:

In such SUSY scenarios, the fine-tuning required to maintain low mass of the electroweak scale can be avoided, and many searches for light top squarks are being pursued at the CERN LHC.

I have changed the meaning of the last part of the sentence, and here I think that it would be appropriate to reference the top squark searches from ATLAS and CMS more broadly. Our papers allow reinterpretation in different models, so my guess is that their results could be relevant to this case as well.

Response: We have changed the wording.

Response 2: Brian can you look if some appropriate references for top squark searches form ATLAS and CMS and give them to me to enter. I think you already did a search.

Comment: L15

that decays to a photon and a gravitino leading to photons in the final state. â†’ suggest that decays to a photon and a gravitino, leading to photons in the final state.

Response: Done

Comment: L18

â€œFurthermore, if the top squark is the only colored particle sufficiently light to be produced at the LHC, SUSY production would proceed through pair production of top squarks.â€

***This is OK, but I donâ€™t see why you need to go this farâ€¦if there were other colored SUSY particles light enough to be produced, you would still have top squark pair production. And natural SUSY certainly allows other light-ish colored particles (~t_2, ~b_L, and ~g). The structure of the paragraph controlled by the fact that you start with the neutralino and gravitino and donâ€™t explain the SUSY production process until the end of the paragraph. So I think that the key role of the sentence here is to state the actual production process assumed â€” you donâ€™t need to assume that it is the only SUSY production process. How about

â€œBecause top squarks are expected to be relatively light in natural SUSY scenarios, we search for top squark pair production, a strong process. [Then as before] Assuming a bino-like NLSP, each top squark would decay to a top quark and a neutralino, with the neutralino decaying to a photon and a gravitino, leading to a ttbar + gamma gamma + pTmiss topology.â€

Response: Done

Comment: L23 â€¦final state of the ttbar pair that requires the presence â†’ suggest â€¦final state of the ttbar pair, which requires the presence of

To me, this makes more sense as a non-restrictive clause.

Response: Done

Comment: L25 ***â€œand an enhanced lepton+jets mode in ttbar decays.â€ Not sure what you are saying hereâ€¦could you please clarify? How is this different from what you just said?

Response: ???

Comment: L27 â€œthat depend on the presence of one or two selected photons in the eventâ€ â†’ suggest â€œ, depending on the presence of one or two selected photons in the eventâ€

Response:

Comment: L30 You define "false photons" on L105, so I donâ€™t see why you also need to do that here. I would just end the sentence at â€œrequirements.â€

Response:

2. The CMS detector

Fine.

3. Event and object reconstruction

Comment: L66 â€œand have transverse momentumâ€ â†’ â€œand to have transverse momentumâ€ [need parallel grammar]

The structure of this sentence is a bit odd. It looks like a 3-time list, but â€œandâ€ appears twice. How about

â€œPhotons are reconstructedâ€¦ , are required to be â€¦, and must haveâ€¦â€ or â€œPhotons are reconstructed . They are required to be isolatedâ€¦and to have [no comma].â€

Response:

Response:

Comment: L88 â€œthereby increasing sensitivity to signal.â€ â†’ â€œthereby increasing the signal sensitivity.â€

Response:

Comment: L90 â€œThe efficiency of selection is aboutâ€¦â€ â†’ â€œThe selection efficiency is aboutâ€¦

Response:

4. Analysis strategy

Maybe this section should be called â€œEvent selection and analysis strategyâ€ ?â€¨

The section starts off with a very detailed discussion of triggers, lepton requirements, and photon requirements. It doesnâ€™t seem like a â€œstrategyâ€ discussion. I think it could be useful to have a 1-2 sentence overview.

There is a discussion of the trigger pT thresholds for the leptons, but the offline cuts are given in the previous section. Seems a bit odd.

Response:

Comment: L103 â€œâ€¦more than one photon candidatesâ€ â†’ â€œâ€¦at least two photon candidatesâ€

Response:

Comment: L106 â€œthat are used to define two control regionsâ€ â†’ â€œand are used to define two control regionsâ€

Response:

Comment: L107 â€œone false and no genuine photons passing all requirementsâ€ â†’ ??? â€œone false and no genuine photonsâ€

Response:

Comment: L108 â€œpassing all requirementsâ€ - again this seems redundant. Or am I missing something?

Response:

Comment: L116 - I don't see anything about GEANT being used to simulate the detector.

Response:

Comment: L130 â€œThe Z+jets and Z+gamma events correspond to small backgrounds in the muon+jets channel originating from the negligible misidentification of muons as photons.â€

It is odd to say that something â€œsmallâ€ originates from something that is â€œnegligibleâ€ . This does not sound consistent. How about

â€œIn the muon+jets channel, the background from Z+jets and Z+gamma events is very small [negligible], because of the low probability for a muon to be misidentified as a photon. In the electron+jets channel, however, these processes contribute more to the background, especially at low pTmiss, because the probability for an electron to be misidentified as a photon is much higher.â€

Comment: Figure 1 caption

***I am confused about the wording â€œand (c) has the result of the fit for SFâ€¦â€ Maybe â€œhasâ€ should be â€œasâ€ ? But the overall wording is awkward. I suggest splitting the discussion of the fit as a separate sentence.

Response:

Comment: L181 ***The formula â€œ(1-Data/Background) is awkward. Is there are better way to do this? Do you even need this?

Response:

5. Results and interpretation

Comment: L194 there is some stray text here: â€œlabelInterpretationâ€ .

Response:

L196 â€œand assumed to beâ€ â†’ â€œand are assumed to beâ€

Response:

Comment: L202 The list here is awkward, because there is a sub-list, but only commas are used. Suggest ended sentence after â€œin MC scale factors.â€ Then start a new sentence

â€œThese include b tagging; electron, muon, and photon identification; and trigger efficiency.â€

So now you can use the ; for the main list and , for the sublist. This is standard.

Response:

Commnent: L204 â€œshown in Fig. 3â€ â†’ â€œas shown in Fig. 3â€

Response:

Comment: ***L207 I don't see anything about whether FastSim or FullSim was used here. Was this privately generated MC?

Response:

Comment: L208 no comma before â€œand NLO cross sectionsâ€

Response:

Comment: L209 a bit odd to see â€œtop squarkâ€ written out as text rather than as a symbol. Why not introduce the symbol in the Intro and use it?

Response:

Comment: L213 â€œare decoupled by setting them to very large masses to forceâ€¦â€ â€¨â†’ â€œare decoupled by setting their masses to very large values. [then start a new sentence]

Response:

Comment: Table 2 caption - "unceraintie" -> "uncertainties"

Response:

Comment: Table 3 In expressions like "(460, 175)" need a space after the comma.

Response:

Comment; L227 Need to make sure that +- doesnâ€™t separate from 100. Can put the whole thing in math mode.

Response:

Comment: L230-L232 It is odd that you do not make any observations or comments about Fig. 4 and Fig. 5.

Response:

Comment: Figure 4 The symbol ~t is used in the figure but not in the text. Actually, it is sometimes used in the figure (in the decay description) and sometimes not (in the inequalities). We need to be consistent in the notation. Note also the x-axis label and the figure caption.

Some symbols seem to be in boldface and others not. I don't see a reason why.
