Discussion question:


1. VBF vs. VH: if production rates are comparable, why look at one and not the other?
   1. Because VBF forward jets are useful for cutting on
   2. MET cuts eliminate VH
1. Muon pt spectrum figure 1 right
   1. Why is relative muon pt spectrum all wavy?
      1. Not clear, probably a fluctuation
   1. Why does ISR lead to a hard mumu pt spectrum?
      1. Higgs recoils against ISR (color factor makes more ISR for g vs. q) 
1. Why is H to mumu interesting
   1. Because leptons (tau and mu) have well defined mass relative to q’s it is a better explanation of how Higgs couples to fermions
1. ROC curves 
   1. Patrick shows a ROC curve, explains how it shows relationship between accepted signal vs accepted background
1. BDT score plots
   1. Why is there a weird peak in the BDT plot? 
      1. Unclear, but probably a fluctuation
1. Signal modeling
   1. CB plus gaussian are phenomenological models that are not fundamental but are used to account for detector resolution effects. This is a common parameterization, as well as Double sided crystal ball
   2. The background is done with a complicated model that is still actively being debated and there is no conclusion about the best shape. This is an ongoing study
