DoubleMuonLowMass primary dataset in AOD format from RunD of 2015. Run period from run number 256630 to 260627.
The list of validated runs, which must be applied to all analyses, either with the full validation or for an analysis requiring only muons, can be found in:
Events stored in this primary dataset were selected because of the presence of at least two muons with low invariant mass.
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:
Global tag: 76X_dataRun2_v15
Configuration file for RECO step reco_2015D_DoubleMuonLowMass
HLT trigger paths
The possible HLT trigger paths in this dataset are:
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:
