Abstract

We report on the accuracy of the measurement of the two photon decay width of a Higgs boson with the mass of 120 GeV at the TESLA Photon Collider, assuming a γγ integrated luminosity of 80 fb^-1 in the hard part of the spectrum. The QCD radiative corrections for the quark pair background processes are taken into account by a reweighting procedure. We found that the product Γ(\rm H → γγ) × \rm BR (\rm H → \rm b \rm b) can be measured with the statistical error of 1.8% in one year of run.
