Higgs Trigger Validation

The cmssw release trigger validation is done within the PdmV group. Each release should be validated, just comparing with some release of reference, and reported each new release period at PdmV Trigger Validation twiki

Code Integration

The code can be found at cvs repository in HLTriggerOffline/Higgs. The tag conventions XX-YY-ZZ are as following:
  • XX: increases by one when the code breaks off with respect the old one. Therefore, the code is incompatible with the last tag. Some examples: trigger paths removed from the hltHiggsValidator_cfi.py, folders (analysis) removed from the validation,...
  • YY: increases by one when new functionalities have been incorporated in the code without breaking it. Code compatible with the last tag. Some examples: trigger paths added to the hltHiggsValidator_cfi.py, folders (analysis) added, histograms or plots added, ...
  • ZZ: increases by one mainly when a bug(s) has been fixed.

Code Validation Process

Compilation and previous checks: using a 5_2_0 release from scratch

In order to check all the code is in good place, with all the needed libraries and so on: downloading from scratch in a clean lxplus environment:
ssh -X lxplus.cern.ch
[duarte@lxplus440:~/scratch0/TEST_CMSSW]$ export SCRAM_ARCH=slc5_amd64_gcc462
[duarte@lxplus440:~/scratch0/TEST_CMSSW]$ cmsrel CMSSW_5_2_0
[duarte@lxplus440:~/scratch0/TEST_CMSSW]$ cd CMSSW_5_2_0/src/  && cvs co HLTriggerOffline/Higgs

So the code compiles fine and is ready to be tested Yes / Done

RelVal Testing procedure. DQM group instructions

For introduce the code in the DMQforMC it is needed to proceed with the instructions found in RelValTesting twiki page. The test procedure is divided in three steps. The procedure has been followed for the Full Simulation. It was run at a lxplus from scratch, so in order to reproduce it in a lxplus don't forget:
ulimit -S -v unlimited
  1. Used the MC sample: /RelValH130GGgluonfusion/CMSSW_5_2_0-START52_V4A-v1/GEN-SIM-DIGI-RAW-HLTDEBUG (Note that if you want to generate your our datasample, you can do it using
     cmsDriver.py SingleMuPt10.cfi -s GEN,SIM,DIGI,L1,DIGI2RAW,HLT:GRun -n 10 --eventcontent FEVTDEBUGHLT --conditions auto:mc --mc --no_exec 
    The SingleMuPt10.cfi file was extracted from Configuration/Generator/python where there are other options...)
  2. Run the combined RelVal+DQMOffline histogramming (step2)
      cmsDriver.py step2 -s RAW2DIGI,RECO,VALIDATION,DQM -n 10 --filein /store/relval/CMSSW_5_2_0/RelValH130GGgluonfusion/GEN-SIM-DIGI-RAW-HLTDEBUG/START52_V4A-v1/0000/34331C19-FE68-E111-A291-001A9281171E.root --eventcontent FEVTDEBUGHLT --conditions auto:mc --mc --no_exec 
    You can search for HLTDEBUG samples in DBS (after initialized the environment with the cmssetup)
    dbs search --query='find dataset where dataset = *RelVal*5_2_0-*GEN-SIM-DIGI-RAW-HLTDEBUG*'
  3. Run the combined RelVal+DQMOffline harvesting (step3)
     cmsDriver.py step3 -s HARVESTING:validationHarvesting+dqmHarvesting --harvesting AtRunEnd --conditions auto:mc --filein file:step2_RAW2DIGI_RECO_VALIDATION_DQM.root --mc --no_exec 

After the steps a root file

DQM_*_CMSSW_X_Y_Z__RECO.root
has been created a filled with the histograms which have been defined. All seems to be OK Yes / Done

Package description

The validation is done between releases by comparing the efficiencies of some selected triggers used by several Higgs analysis. These efficiencies are calculated as follows,
  • DENOMINATOR pt,eta,phi of the gen/reco objects (which pass some analysis dependent requirements)
  • NUMERATOR pt,eta,phi of the gen/reco PASSING the monitored trigger

The efficiencies calculations are done for HWW, HZZ, H, Htaunu, H2tau and Hbb, analysis within the Higgs PAG. Actually, and in the context of MC release validation, the efficiencies are going to be calculated in events which contain the objects of interest in each analysis, where have been applied some loose and minor cuts. A set of the more critical triggers for each analysis are being monitored whenever a new release is introduced. After consulting the trigger experts, the trigger paths to be monitored are: ( STILL IN PROCESS TO BE DEFINED )

The trigger paths also can be found, and probably with the latest changes, on this spreadsheet

Configuration

The hltHiggsValidator_cfi.py configuration file is the place where to include the path to be monitored

Validation: defining the baseline release

After put the new code in place and define the trigger paths we want to monitor, we have to define the baseline plots which are going to be used as reference. We have to found a release we agree is ok: 5_2_2 has been validated by all the other PAG/POG, so we would assume it is ok. The samples needed to be able of validate all the channels are not fully defined, trying to do it here:
Analysis GEN/RECO objects involved RelVal Sample Availability
HWW electrons, muons -------- H165WW2L config python
HZZ electrons, muons -------- H200ZZ4L config python
Hgg photons /RelValH130GGgluonfusion GEN-SIM-RECO, GEN-SIM-DIGI-RAW-HLTDEBUG
Htaunu taus, MET (neutrinos) ?? GEN-SIM-RECO, GEN-SIM-DIGI-RAW-HLTDEBUG
H2tau taus /RelValHiggs200ChargedTaus GEN-SIM-RECO, GEN-SIM-DIGI-RAW-HLTDEBUG
Hbb jets, leptons, MET,... /RelValTTbar GEN-SIM-RECO, GEN-SIM-DIGI-RAW-HLTDEBUG
