next milestone (post Period D) - and toward the results in Moriond recommendation

[YasuyukiOkumura]

Dear Gabriel and Brian,

I summarized information in order to restart the Z+b-jet activity
Feel free to add and modify the information, and let's have a meeting to set the strategy up
( who will do what and by when? ) when everyone has time!

selection criteria harmonization

Shall we restart with p3 criteria? https://indico.cern.ch/event/449765/contribution/4/attachments/1163086/1675523/ZJet_Zbjet_insitu_update_JetEtmiss_30thSep.pdf

I guess the current electron channel is the easiest one to apply for our case, i.e.

• pT_{2}<min(15, 0.2*pT_{1})
• delta phi < Pi - 0.5
• Z mass window 15 GeV

TO DO LIST

• implement the uncertainty
  • lepton energy scale
  • lepton energy resolution
  • b-tag SF uncertainty
  • different generators (Powheg vs Sherpa)
• implementation of bootstrap tool
• have preliminary "complete" results

Time scale

The primary target will be including our results in Moriond recommendation.
This will need to be ready for collaboration in Christmas time scale,
and we need to have the results by the biggining of December with full data set!
