Measuring the two-photon decay width of intermediate-mass Higgs bosons at a photon-photon collider

Measuring the two-photon decay width of intermediate-mass Higgs bosons at a photon-photon collider

The feasibility of a measurement of the partial decay width of the intermediate-mass Higgs boson into two photons at a photon-photon collider is studied by a simulation. The QCD radiative correction for quark pair background processes is taken into account for the realistic background estimation. It is found that the …
