Input data file:
- Converted to NanoAOD from 2012 CMS open data:
- root://eospublic.cern.ch//eos/root-eos/benchmark/Run2012B_SingleMu.root (16 GiB, 53 million events)
Tasks:
- Plot the ETmiss of all events.
- Plot the pT of all jets.
- Plot the pT of jets with |η| < 1.
- Plot the ETmiss of events that have at least two jets with pT > 40 GeV.
- Plot the ETmiss of events that have an opposite-charge muon pair with an invariant mass between 60 and 120 GeV.
- For events with at least three jets, plot the pT of the trijet four-momentum that has the invariant mass closest to 172.5 GeV in each event and plot the maximum b-tagging discriminant value among the jets in this trijet.
- Plot the scalar sum in each event of the pT of jets with pT > 30 GeV that are not within 0.4 in ΔR of any light lepton with pT > 10 GeV.
- For events with at least three light leptons and a same-flavor opposite-charge light lepton pair, find such a pair that has the invariant mass closest to 91.2 GeV in each event and plot the transverse mass of the system consisting of the missing tranverse momentum and the highest-pT light lepton not in this pair.
