Data taking / HLT
The collision data were assigned to different RAW datasets using the following HLT configuration.
Data processing / RECO
This primary AOD dataset was processed from the RAW dataset by the following step (identical to 2011 RunA):
Step: RECO
Release: CMSSW_5_3_7_patch5
Global tag: FT_R_53_V18::All
Configuration file for RECO step reco_2011_BTag
HLT trigger paths
The possible HLT trigger paths in this dataset are:
HLT_BTagMu_DiJet110_Mu5
HLT_BTagMu_DiJet20_Mu5
HLT_BTagMu_DiJet40_Mu5
HLT_BTagMu_DiJet70_Mu5
During data taking all the runs recorded by CMS are certified as good for physics analysis if all subdetectors, trigger, lumi and physics objects (tracking, electron, muon, photon, jet and MET) show the expected performance. Certification is based first on the offline shifters evaluation and later on the feedback provided by detector and Physics Object Group experts. Based on the above information, which is stored in a specific database called Run Registry, the Data Quality Monitoring group verifies the consistency of the certification and prepares a json file of certified runs to be used for physics analysis. For each reprocessing of the raw data, the above mentioned steps are repeated. For more information see:
