The feasibility of a measurement of the partial decay width of the intermediate-mass Higgs boson(MH=120 GeV ) into two photons at a photon-photon collider is studied by a simulation. It is found that the two-photon decay width can be measured with the statistical error of 7.6% with the integrated luminosity of 10fb-1. We also discussed a possibility toward further improvement with sophisticated b-quark tagging technique.

The Standard Model

As part of the search for new physics beyond the Standard Model, we chose the determination of the Higgs boson decay width as one of the least experimentally determined values. The decay widths into the four fermions of the lightest and heaviest CP-even Higgs bosons of the THDM model were calculated, taking into account QCD and electroweak corrections in the NLO approximation. To achieve this goal, the program Monte Carlo Prophecy 4f with special scenarios of parameters, 7B1 and 5B1 were used. It was found that the decay width of the heavier CPeven Higgs boson H differs from HSM by 1227.93 times and changes to a negative value when deviating from the standard scenarios. Scale factors kZ2 and kW2 showed the predominance of the associated with Z boson production cross section of CP-even Higgs boson over the associated with W production cross section.
