Abstract

We study double Higgs production in photon-photon collisions as a probe of the new dynamics of Higgs interactions in the framework of two Higgs doublet models. We analyze neutral Higgs bosons production and decay in the fusion processes, γγ→SiSj, Si=h0, H0, A0, and show that both h0h0 and A0A0 production can be enhanced by threshold effects in the region Eγγ2mH±. Resonant effects due to the heavy Higgs H0 can also play a role in the cross section enhancement when it is allowed to decay to two light CP-even h0 or to two light CP-odd A0 scalars. We have scanned the allowed parameter space of the two Higgs doublet model and found a vast region of the parameter space where the cross section is 2 orders of magnitude above the standard model cross section. We further show that the standard model experimental analysis can be used to discover or to constrain the two Higgs doublet model parameter space.
