Light Higgs-boson production at the Photon Collider at TESLA with an improved background analysis

Abstract
Measurement of the Gamma(h -> gamma gamma)Br(h -> b bbar) at the Photon Collider at TESLA is studied for the Standard Model Higgs boson with mass of 120 to 160 GeV. The NLO estimation of background, analysis of overlaying events, realistic b-tagging and corrections for escaping neutrinos were performed. We find that for M_h = 120-160 GeV the Gamma(h -> gamma gamma)Br(h -> b bbar) can be measured with a statistical accuracy of 2-7% after one year of the Photon Collider running.
