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:

1. Plot the E_T^miss of all events.
2. Plot the p_T of all jets.
3. Plot the p_T of jets with |η| < 1.
4. Plot the E_T^miss of events that have at least two jets with p_T > 40 GeV.
5. Plot the E_T^miss of events that have an opposite-charge muon pair with an invariant mass between 60 and 120 GeV.
6. For events with at least three jets, plot the p_T 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.
7. Plot the scalar sum in each event of the p_T of jets with p_T > 30 GeV that are not within 0.4 in ΔR of any light lepton with p_T > 10 GeV.
8. 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-p_T light lepton not in this pair.
