Pseudoscalar Higgs boson pair production at a photon–photon collision in the two Higgs doublet model

Öz:

In this study, the direct pair production of the pseudoscalar Higgs boson at a γγ collision is analyzed inthe context of the two Higgs doublet model (THDM), taking into account the complete one-loop contributions. In orderto illustrate the effect of the new physics, four benchmark point scenarios, which are consistent with theoretical andcurrent experimental constraints, are chosen in the type-I THDM with an exact alignment limit. The effect of individualcontributions from each type of one-loop diagram on the total cross-section is examined in detail. The dependence ofthe cross-section on the center-of-mass energy is also presented at the various polarization configurations of the incomingphotons. Moreover, the regions m212−tan β and mA −tan β in the parameter space of the THDM are scanned for somefixed values of other parameters. The box-type diagrams make a much bigger contribution to the cross-section than theothers at high energies. The total cross-section can be enhanced by a factor of two thanks to opposite-polarized photonsas well as threshold effects.
