2021 03 29

  • ZZ MC status
  • Nearly ready, test tar balls running
  • Will request both Run 2 and Run3 MC

t would be good to have a gridpack job successfully complete before officially requesting the samples.   It sounds like we may be close or  maybe since last week it completed.   Please update me on the status.   However, I think we can at least begin discussion with the contacts.  The contacts are listed at https://twiki.cern.ch/twiki/bin/viewauth/CMS/TWikiSMP#SMP_contacts

 I think we want to request both Run 2 and Run 3 samples.   

   Right now the working ZZ analysis we have is based the code that He is using that was inherited from previous published ZZ analysis.   We want to add the polarization variables and design a polarization fit based on an analysis framework that we know works and that means having something that works on Run 2 data.  Further itís unclear how fast Run 3 data will be available in the usable format so I think it makes sense to work on Run 2 data.   If Run 3 data becomes available the optimal thing would be to add it to the Run 2 data rather than do a completely separate analysis.

  If we could get a decent MC sample quickly enough it may be possible to include a cos(theta *) distribution and a polarization fit into the analysis He is working on.   However, that might not be the best match with the physics content of the paper he is working on.   Physics wise, an analysis that concentrated on Polarization, both SM and new physics applications, would make more sense.

 Just this week the SMP group asked for people to make MC requests.   See the news talk at https://indico.cern.ch/event/1007569/
So we should email the SMP MC contacts and get started on making a request immediately.   I would just email them, state where we are producing the grid pack, and ask them what they need.    At the same time we can ask a second question about the schedule for Run 3 MC.

  • Prelim restructuring
Yesterday Kevin, Sridhara and I discussed that in the new prelim talk format the students are no longer tested as extensively, or at all, on their knowledge of the the CMS detector and the SM.  Based on our discussion here is a proposal for what to do to ensure our students receive adequate training on these subjects.

Each student approaching their prelim will give a talk to the group discussing the SM, placing their analysis in the context of the SM, and discussing the LHC and the CMS detector, including discussion of any detector work they have done and similarly explaining how their analysis uses the detector.   The whole group, but specifically newer students, will be invited to attend.   If necessary the talk can be followed by a closed session for the Profs to ask additional questions.

In preparation for these series of talks various group members will do the following.

1) The last few students to give prelim presentation with a long form SM and detector sections will make their slides available.

2) Those slides will be used to make a template for the talk.  Future students will be encouraged to update and improve the template.

3) Matt will assemble the list of questions he drew up his students and Usama to form a study guide on the SM and CMS.

4) The Prof. team are encouraged to update and improve the study guide.

After this work is sufficiently complete Ho Fung will give the first talk.

  • Rivet SMP-20-007 PAG approved
  • Understood which plots to use for comparison
  • L2 pag approved


2021 03 30

  • IR B2G-20-002 submit

  • CDF W mass
  • Questions asked about issue with DOF background
  • Large but opposite fixes
  • May be expected
  • Asked authors to thing about uncertainty.

* MBI CMS analysis

  • List of CMS analysis

Here is a list of CMS analysis.  I think there has been more.   Some themes of interest at CMS are

1) A few analysis with polarization.  This includes one analysis that uses polarization to enhance the sensitivity to aC in an EFT interpretation.
2) A nearly complete set of EWK production analysis.   Only os WW is missing and might be filled in by that time
3) A fair number of complete Run 2 analysis often including more differential distribution and/or higher order MC comparisons
4) Some interesting oddball analysis like dibosons at 5 TeV and DPS WW.

Iím not sure what you would extract from this in terms of which collaborations might want which talks.   It might be better to start from the perspective of identifying speakers.

Maybe we can neglect VBS V production, Higgs and only have one new physics talk in order to make room for some of the more interesting specific topics that have been covered.

- cheers - matt
