Search for chargino and stop (2LOS) with Run2 data

Comments from 27 November 2020 presentation ( Link to Indico):

The content in the AN-19-256 referred to in the following answers has been implemented in v2. Linked to be updated when when the note v2 is uploaded.
  • Triggers used -> just to put in the AN (planned)
    • Included in the Appendix B of AN
  • Same sign: would it be possible to include this CR in the fit and let it decide?
    • As a first approach, use a non-prompt SF = 1 +/- measured deviation:
      • Checked; no significant changes found for neither the Stop( Contour) nor the Chargino (Contour). found to change significantly
    • Think if easy to add the CR in the fit in a smart way
      • Currently implemented for WZ, ZZ and ttZ: Stop(Contour), Chargino (Contour),
      • Same sign currently not considered as it affects as a component to each background rather than as a background itself.
  • DY mismodeling: how it affects the fit?

    • Limits using no-smeared DY as central shape
      • Checked; no significant changes found for neither the Stop( Contour), or the Chargino (Contour).
    • Estimate DY in signal region.
      • Yields tables in section 7 of the AN
  • Dependence of background SFs on search region bins.

    • Explain well the jet rate parameter
      • To be added in the AN.
    • Add variables
      • Jets -> so far only ZZ
        • Variables in place, currently being studied
      • Ptmiss -> already have but we can add it with SR bins
        • Variables in place, currently being studied.
