df102_NanoAODDimuonAnalysis.C File Reference

Detailed Description

This tutorial illustrates how NanoAOD files can be processed with ROOT dataframes.

The NanoAOD-like input files are filled with 66 mio. events from CMS OpenData containing muon candidates from 2012 data (DOI: 10.7483/OPENDATA.CMS.YLIC.86ZZ and DOI: 10.7483/OPENDATA.CMS.M5AD.Y3V3). The script matches muon pairs and produces an histogram of the dimuon mass spectrum showing resonances up to the Z mass. Note that the bump at 30 GeV is not a resonance but a trigger effect.
