Higgs Recoil Mass Measurement and ZH Cross Section Tim Barklow, Awatif Belymam SLAC Feb 24, 2009

Simulation  CM Energy: 250 GeV  Higgs mass: 120 GeV and GeV  Signal 250 fb -1 : +80e-__-30e+ 125 fb -1 : +80e-__-30e+ and -80e-__+30e+ 300,000 events  Background 7M events

Analysis  Higgs Recoil Mass:  Cross Section:  Estimation of measurement accuracies of the Higgs mass and σ(ZH)

Event Selection

Reconstructed recoil mass  Muon channel, 125 fb -1 A peak is observed at 120 GeV for signal events

Recoil mass  Muon channel, 250 fb -1

ZH Cross-Section

Measurement accuracies  Measurement accuracies for muon channel  Measurement accuracies for electron channel
