+ | * Experimentally H->gammma gamma makes more sense fully background subtracted | ||
+ | * H->ZZ->4l or H->WW->2l2nu could give measurements including irreducible background (with appropriate fiducial phase space definition including eg suitable m4l window in that case) | ||
+ | * In that case prediction for irreducible background should also be provided to allow theorists to easily subtract it if desired | ||
