Recasting/fastsim comparison

Members: Ben F, Andy B, Sezen S, Jon B, R. Ruiz, Anders K, Are R., Nishita D., Philippe G., Tomas G…

  • Finish comparisons on particularly leptonic channels and busy environments
    • Benj: The analysis is now implemented, but not yet validated, in MA5. Are there common events available somewhere (google drive or CERNBox)?
  • Comparisons between MA5 (Delphes/Superfast)/Rivet/CheckMATE/ColliderBit
  • Compressed SUSY: ATLAS soft dilepton + soft tracks? ATLAS-CONF-2019-014?
  • CMS Razor (Sezen)

Recast comparison with CMS SUS-16-048

We'll use the published version of CMS SUS-16-048: http://cms-results.web.cern.ch/cms-results/public-results/publications/SUS-16-048/index.html

Our benchmark point will be the (150,142.5) test point from CMS, i.e. degenerate and pure wino Chi20/Chi+1 at 150 GeV, and a pure bino Chi10 at 142.5 GeV.

The CMS signal simulation uses Pythia (8.212) to decay the Chi20 and Chi1+. They assume SM branching ratios for the resulting virtual Z and W, but take into account the Breit-Wigner shapes. To make this work in Pythia we assume that they have adjusted the “23:mMin” and “24:mMin” settings. We'll try with

  • 23:mMin = 1
  • 24:mMin = 1

250k events will be produced and stored in HepMC format.

Comparison with experiment simulation software

CMS software (simulation and reconstruction) is public and can be used to be compared with results from Delphes and smearing-based simulation.

Events will be stored in Delphes format.
