qqH,llH only:
Evis<140 GeV and only idrup = 106577 for the background:
Potential tools for reducing the 4f_WW background:
- higher cut on number of charged tracks (unlikely to help S)
- extra cuts but keep any event that has high B-likeness
- redoing n-tuples adding variables for jet combos consistent with W decays (IN PROGRESS)
Note concerning ZZ background: wider cut on acoplanarity should help^TrackSubdetectorHitNumbersDriver.java|||\
