This is a repository for (bacon bits > histograms > limits) common to DAZSLE analyses, i.e. an attempt to consolidate the divergent branches of ZPrimePlusJet. No analysis-specific code should be added.

C++ classes:

• Class BaconTree: TTree:MakeSelector()s for bacon bits
  • Derived class BaconData adds some useful functions, like selecting the jet of interest and computing N2DDT.
• Class HistogramManager: utility class for managing histograms.

python modules:

• python/rhalphabet: original rhalphabet code from 2016 H(bb) analysis
• python/combine_helper: python package for constructing Rhalphabet datacards (based on original rhalphabet code, intended for better flexibility with multiple SRs)
• python/analyzer:
  • Class AnalysisBase: defines an interface for bacon -> histograms step.
  • Class Cutflow: base class for EventSelector, defining cutflow and N-1 histogram functionality.
  • Class EventSelector: class for performing a sequence of event-level cuts on BaconData. (Cuts are added with decorators, see https://github.com/DryRun/PhiBBPlusJet/blob/zqq/analysis/histograms.py for an example)

python helpers:

• python/cross_sections.py: cross sections of MC samples
• python/seaborn_colors: provides colors from the Seaborn module.

Data:

• data/SimpleN2DDT: 3D histograms (N2 vs pt vs rho) from QCD MC for computing simple N2DDT on the fly

Wish list:

• Cristina's new N2DDT code
• N2/double b-tag/mass scale factor code? This might be worth its own repository.
