X → HH → 4b

  • Separate HH SR from ZZ and ZH
  • [ ] Check modeling in SB (ZZ)
  • [ ] Check modeling in mixed data SR after SvB Cut
  • [ ] Check bias of SvB cut
  • [ ] Refit SvB with decorrelation in mHH
    • [ ] Will want to keep ZZ/ZH/HH signals too
  • [ ] Systematics from mixed data
  • Whence the double peaks in mHH ?
  • Near term plan:
    • Extend mass rage to 200 - 1200 GeV
    • Separate closure tests in mixed data ZZ ZH and HH regions
    • Do fit background only in unblinded ZZ SR
    • Present background modeling in B2G
  • Longer-term / In parallel :
    • Get signal samples picos
    • Do blinded signal + bkg fit in HH SR
    • Get limits vs mass
    • Plot SvB in HH SR
    • Determine if can gain with a SvB cut
    • Present in B2G (Determine publication plan)

X → YH → 4b

  • 2D Brute force scan
  • Solve jet-pairing combinatorics
  • How to unbias FvT in scan
    • Clever way without brute force refit ? (right to be forgotten)

Semi-supervised

  • Seeing Bias in 2d mass plane after plotting upper tail.
  • Plot lower tail.
  • How important is it to cluster in the mass mass plane after a DvB cut ?
