TL;DR
This paper explores how photon colliders can test specific Higgs couplings to distinguish between the Standard Model, Two Higgs Doublet Model, and MSSM, focusing on a 100 GeV Higgs boson.
Contribution
It analyzes the effective couplings hZγ and hγγ in different models and demonstrates their potential to differentiate these models at photon colliders.
Findings
Couplings vary significantly across models.
Photon colliders can effectively test these couplings.
Distinguishing models is feasible with precise measurements.
Abstract
We consider the two effective couplings hZ\gamma and h\gamma\gamma involving a neutral scalar Higgs boson with a mass around 100 GeV in the Standard Model, in the Two Higgs Doublet Model, and in the Minimal Supersymmetric Standard Model. The couplings can be tested at Photon Colliders, and used to distinguish these models.
