tuning MVA cuts for lowPt and tobTec #10086
Conversation
The problems can be seen here (high dxy efficiency loss): http://cmsdoc.cern.ch/cms/Physics/tracking/validation/MC/CMSSW_7_5_0_pre5/MCRUN2_75_V5_PU_highPurity_25ns/RelValTTbar/effvspos.pdf |
A new Pull Request was created by @mhwalker (Matthew Walker) for CMSSW_7_5_X. tuning MVA cuts for lowPt and tobTec It involves the following packages: RecoTracker/IterativeTracking @cmsbuild, @cvuosalo, @slava77 can you please review it and eventually sign? Thanks. |
Let's go with this, we can retune later... |
@slava77 Correct, no payload changes, only changing the cut value. |
The tests are being triggered in jenkins. |
(NB: my plots were in a comparison with 750pre6 [black]) |
This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_X IBs once checked with relvals in the development release cycle of CMSSW (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar |

tuning MVA cuts for lowPt and tobTec
Retuned LowPtTripletStep highPurity MVA cut to remove the step in the chi2 distribution - it pretty much disappears.
Retuned TobTecStep highPurity MVA cut to recover some efficiency at high dxy. Most efficiency lost for dxy < 50 cm recovered.
