Noise peak is smaller with tighter time cuts while pi0 peaks do not change: it will allow us to discriminate real pi0 peaks and noise peaks smile Launch trains with inverse time cut to study noise peaks clusters topology.

Train launched on the grid Calib with tender on no bad map with inverse time cut

BACK TO CALIBRATION List of weird towers checked by eye for LHC15ij TENDER on + time cut applied (see trains 399 and 400):

PbTower.rtf: List of problematic towers

Now it is hard to say if noise remains or if we see low mass peak towers

Example where noise peak disappear compared to pass3_DCALAndThirds: 13_2_13, 15_17_4, 15_22_14, 15_22_18, 17_6_19

For smearing

Use Landau distribution (Landau(x,0.05,0.02)) for random number for only 20% of the clusters. Weird behavior at low M02 where smearing do not depopulate bins: only 15% goes after the pic, but do not explain all the effect.

Efficiency curves done for signal and bkg. They are different for signal and bkg for isolation condition mainly. How to deal with tiny variation on M02 efficiency. Does it mean that the systematic effects due to this parameter are small on purity ? No sure this is what we see.

BONNE ANNÉE !!

TO DO LIST

Do xE exponential fit with and without I option in fit to have extreme slope values
Check exponential fit takes into account barycenter of bins ->DONE good fit option set in fit "I": Use integral of function in bin instead of value at bin center found in ROOT documentation
Invariant mass subtraction : do plot contribution with gamma decay paired and not gamma decay -> DONE now we clearly see the gamma paired contribution is not higher than 15% at low pT. Plots are here: /Users/vauthier/Documents/These/AnalyseGHCorr_pp_2014/SummaryNotes/PurityJulien/MacrosToDoChecks
See invariant mass peak in simu -> ONGOING
Which impact on xE distribution when cut invariant mass window
Put this in analysis note -> ONGOING
Check bug in p4 -> ONGOING
Check if f_isol is the same for different M02 regions for one pt bin
See effect on smeared simu on f_isol
Do systematics -> ONGOING
Change plots in AN with sum pt condition for purity

For systematics:

Efficiency's cuts have been done. Efficiency is the proportion of signal before the cut over the total amount of signal for a given cut distribution see here : /Users/vauthier/Documents/These/AnalyseGHCorr_pp_2014/PurityCalculations/SystematicsStudies

TM cut gives significantly different efficiency than isolation, anti-isolation and M02 cuts. How to deal with that ?

Discussed with Julien : REDO TM cuts was not correct -> DONE + do efficiency for M02 for bkg and anti isolation

Found the old study on residuals. It was a different .root but same result. The behavior disappear when looking at non log scale.

15 Dec 2015

Check of normalisation of f(xE) : for all periods and pt bins Nicolas is 0.96 and p2 is 0.72 -> keep looking if errors

14 Dec 2015

TO DO LIST :

Check xf(x) integral is equal to one (normalisation of function)
Check exponential fit takes into account barycenter of bins
Invariant mass subtraction : do plot contribution with gamma decay paired and not gamma decay
See invariant mass peak in simu
Which impact on xE distribution when cut invariant mass window
Put this in analysis note
Check bug in p4
Check if f_isol is the same for different M02 regions for one pt bin
See effect on smeared simu on f_isol

Discussion

Invariant mass cut : if we cut all the windows we cut gamma decay but also direct gamma. The important thing is to know what's the efficiency of such a cut (is CB dominant or not). If the peak is well defined we will have a little uncertainty in purity estimate at low pt but in other cases we would not gain anything. Add this in analysis note.

Fit on f_isol can be performed only in M02 regions where the pi0 are.

1 Dec 2015

Analysis note

implementation of Julien's comments done (except purity messy page)
begin review of inv mass and xE parts

pi0 calibration

restart when time calibration is available
no more issue for compiling -> try to implement energy plot tomorrow

Quantum mechanics lectures

all TDs are prepared
start thinking about exam

26 Nov 2015

Freestyle seminar : use previous slides but lighter and with EV from run 2 + discussion on what's going to happen during run 2 TD4 MQ : cannot simplified matrix element due to CNM. (Lagrangian is not the same for lonely neutron and neutron in tritium). Tensorial product : AcrossB = [ai,jB]

25 Nov 2015

LED runs

ampSig[] is not empty just before treeEv->Fill(). Hence I suspect there is a problem while filling, maybe due to declaration or instantiation of the branch ?

Try to implement Energy distribution for problematic towers but cannot test in local mode. AliPhysics do not compile due to SetTimeCalibration() function in AliEMCALClusterizer and IsTimeCalibrationOn in 'AliEMCALRecParam. Wait until new tag to see if it compile, otherwise send an email to taskforce

24 Nov 2015

Fake dead regions do not change calibration factor -> no bias seem to be given with towers masked

23 Nov 2015

LED runs

Problems come from branch booking. Work on going

Calibration

Put fake dead regions in EMCAL to study bias in fit :

SM 1 and 3 : col 28->39, row 0->7
SM 2 and 8 : col 0->3, row 8->15

Trains on the grid nb 198 and 199

18 Nov 2015

I've found a match between martin's macro and ours. For this we have to remove all the cut on fRawAnalyzer and rawUtils. I also saw that SetIsZeroSuppressed(true/false) does not change the amplitude of the fit.

17 Nov 2015

Past month : crazy month only EMCal pi0 calibration. Some issues were found :

SM 18 and SM 19 HV were switched after cosmic calibration at Grenoble
The new HV biases will have the corrected HV for towers with no info on pi0 calibration and the HV find with pi0 calibration
The LED runs are not really trusted. For now we don't fully understand what we see.
The pi0 calibration will be improved as the HV scans and LED runs technics
Meeting with Eliane, not very clear where she stands for me. We were clear about p-Pb and possibly Pb-Pb with new student

Now :

Resume with analysis note, p4 and systematics
Continue with calibration stuffs in parallel

Mapping convention for EMCal and DCal : https://twiki.cern.ch/twiki/bin/view/ALICE/EMCalCalibConventions. In NewBias.txt file (under /cebaf/cebaf/EMCAL/calibPi0_run2/recalculateHV_4_with2015data/output_HVrecalculation_pass2_handMadeFinalCorrections_createSetBiasScripts/SMxxx) the row 0-7 stand for side C for DCal (SM19) and side A for EMCal (SM10).

All details on pi0 calibration can be found here : https://twiki.cern.ch/twiki/bin/view/ALICE/EMCalCalibrationPage.

Details on the procedure are explained here : https://twiki.cern.ch/twiki/bin/viewauth/ALICE/EMCalPi0CalibHowTo

02 Sept 2015

To be discussed

Looking at ATLAS paper for prompt photons xsection : it seems they also choose sum pT. Regarding pT max and sum pT distributions it seems pT max will be more efficient to cut decays photons. re look at this to be sure

Why isolation fraction are different using TH2F pTLead vs M02 instead of TH1F pTLead only ?
