A study of the measurement of the two photon decay width times the branching ratio of the Standard Model Higgs boson with a mass of 120 GeV in photon–photon collisions is presented, assuming a γ
γ integrated luminosity of 80 fb−1 in the high energy part of the spectrum. The analysis is based on the reconstruction of the Higgs events produced in the γ
γ→H process, followed by the decay of the Higgs into a
pair. A statistical error of the measurement of the two-photon width, Γ(H→γ
γ), times the branching ratio of the Higgs boson, BR
is found to be 2.1% for one year of data taking.
