Description

Here we address the results of a full simulation of experimental measurement of the Standard Model Higgs boson decaying to a pair of photons at 3 TeV center-of-mass energy at the Compact Linear Collider (CLIC). Since photons do not couple to Higgs boson at a tree level, any deviation of the Higgs to photons coupling may indicate a New Physics. We show that the product of the Higgs production cross-section in W+W− fusion and BR (H → γγ) as the observable for determination of the Higgs to photons coupling, can be measured with a relative statistical precision of 5.5%, assuming the integrated luminosity of 5 ab−1 and unpolarized beams.
