SM Higgs Channels
WH ? l? bb backgrounds Wbb, WZ, tt, single top
- factor ~ 1.3 improvement in S/B with neural network
- possibility to exploit angular distributions (WH vs. Wbb) Parke and Veseli, hep-ph/9903231
WH ? qq bb overwhelmed by QCD background
ZH ? l l bb backgrounds Zbb, ZZ, tt
ZH ? ?? bb backgrounds QCD, Zbb, ZZ, tt
- requires relatively soft missing ET trigger (35 GeV?)
gg ? H ? WW* backgrounds Drell-Yan, WW, WZ, ZZ, tt, tW, ?? signal:background ratio ~ 7 ? 10-3 !
- Angular cuts to separate signal from “irreducible” WW background
