ChargeReco

Production of extended nanoAOD ntuples for analysis and training of b jet charge classfier.

Tests are defined in test/runCMSSWTest.sh

Produce extended nanoAOD files

Configuration file for full Run 2 UL extended nanoAOD ntuple production.

cmsRun ChargeReco/NANOProducer/test/produceNANO.py

The cfg accepts the following options:

• isData specifies if NanoAOD for data or MC is produced. Besides others MC will contain extra truth-level information (default: 0 = MC).
• year controls the global tags and eras. Possible values are: 2016, 2016preVFP, 2017, 2018 (default: 2016).
• addSignalLHE extracts and stores weights from the generator that are used to reweight the signal sample to different top quark widths (default: False).

job submission

in crab folder run e.g.:

python2 submit.py -i datasets/data_2017.txt -y 2017 -v 2022-03-01_v6 --data

use --dry to skip job submission and only generate submit scripts

Brief package overview

• DataFormats: Contains classes for all persistent information, input features (JetChargeTagFeatures) and labels (JetChargeLabel), to be saved inside edm::Event.
• NANOProducer: Producers to create additional FlatTables to be stored inside flat nanoAOD format.
• JetChargeInfoProducer: Producers to extract relevant jet features and labels.
