CMU bbWW

• AK: Gave good talk on Wednesday

• AK: some plots on rebinnig

• Talked about what it would take to do ttHbb with our analysis
  • Could probably just reuse FvT
  • refit SvB (reuse architecture) (Maybe want attention at b-jet level not dijet..)

• AK: discussion of weather CMS corrects jet energies based on energy fractions (EM vs Had)

... Seems they do not TB: ATLAS Jet Calibration and the Global Sequential Calibration (Run 1)

• Matteo has QCD "all the way down".

• Chat about the cluster
• AK: Trainging the 3jet classifier

• Me and Aniket
• He has a lot now in place… neeed to start orgainizing it for a talk.

• Matteo ttH … still using QCD MC :(

• Not much
• Sena moving on to a different analysis … :(

• AK almost has the the analysis setup

• Discussion of opus vs sonnet

• AK: Progress
• MM: How are they "killing QCD" There SR is our fourTag region ! They should use our mixed data

• AK: great progress on the mass regressor… looks like we can regress mHWW!
• Not much else

• Short and sweet

• Lots of good slides from AK
• Need a way to reconstruct the higgs mass

• Aniket new SRs.
• AGE working on cluster

AK: Talk of SR definitions has data and MC files… Will send to me

• Next steps:
  • Update the code with histogrmas of the clasifier outputs
  • Make pltos of all the backgroup vs signal
  • Make pltos of data vs background

• AK: Lots of good classifier studies

• AK: good progress on the classifier
• JA: good progress on the processor

AE: 4b work AK: Classifier running JA: Plots MM: ttH Hadronic SD:

• AE: getting code running
• AK: Chat re:classifier

• AK: Updates on MC and SR
• AE: updating code
• JA: will add plotting

• Discussed setting up the nominal selction
• The dominate sensitivity in the nominal analysis comes from 3j+2b
• So far we have been comparing against 4j+2b

• Aniket fixes chi2 plots
• Chat re:ttH worth it.

• Skims mostly done
• Chat about next steps

• Will reply to the previous mail

• Aniket to give update in next meeting
• Implementing unit tests
• Will move to new version of coffea

• Discuss adding in quadrature

• Submitting Samples…not going welll
• Should setup a friend tree maker instead
• Sam found bug in Aniket's code… gain in low pT much better than originally thought.
• Will prepare slides

• AE: has scripts to make low pt jets
• Aniket has 1st draft of new processor

• Coffea25 code runing 10x faster than before
• will ping FNAL re:code structuring
• will ping Fikri re:Run3 samples

• AE: has nano recipe from Frikri … only goes down to 15 GeV… iterating.
• AK: setting up new coffea framework
• Plan to meet with coffeea experts to discuss framework setup

• Will start moving to new coffea version and to run3

• Aniket to give slides next meeting

• Prep talk for bbWW

• Not much. Chi2 using mean of the signal distribution !

• AE: Running jobs
• AK: will debug w-mass constraint by trying to fit by hand… Sam will help
• SD: running on lxplus

Aniket

• Will add unit test to do the neutrino reweighting Alejandro
• Calibration results for all years

• Aniket: Processor too slow… b/c running all systematics. Will turn off.
• ttbar Chi2 now looks good.
• Not much else…

• Aniket: getting the new processor going
• AGE: discussion of working with ETH
• Not much else

• Aniket still sees weird chi2 problems
• Needs to define the W*->qq vs W->qq using the truth information

Aniket

• Chi2 scale off will remake (likely bug)
• Will start making comprehensive slides
• Discussion of various chi2 terms

Aniket

• Bug in w-mass constraint
• Will make X_HH and X_tt
• Separately for W* -> qq and W->qq
• For W*->qq: X_HH include mass terms for both higges

• For W->qq: Only have H->bb can try adding mT leptonic W and pZ neutrino

  Alejandro

• Has JEC corrections in hand
• Will present to JERC in two weeks and ask about need for JER

Aniket

• Good plots
• mTop looks buggy, signal at ttbar are too close.
• mH looks OK

• WIll update slides with jet selection

  Sam

• looking into s vs B

  Sena

• progress on code

• Only aniket
• Making good progress!

• https://indico.cern.ch/event/1432491/
• Can sign up on: cms-hh-bbvv@cern.ch
• Alejandro
  • Has response scale corrections.
  • What about resolution ? Will look into
  • Trying to use Matteos processor, but problem with saving histograms
  • (Will not make it next meeting)
• Sena
  • Back from holidays
  • Problem running on the Korean cluster
• Aniket
  • fix for Wasnt plotting the tru
  • Looks like the Higgs mass plots are switched.
  • Post slides to agenda.
• Sam
  • Making progress on plotting

• Comparing the top 3 qvsq jets
• Looking into the leading p_t. Can probably require only the leading to be
