Özet:

 

In this study, the direct pair production of the pseudoscalar Higgs boson at a γγ collision is analyzed in  the context of the two Higgs doublet model (THDM), taking into account the complete one-loop contributions. In order  to illustrate the effect of the new physics, four benchmark point scenarios, which are consistent with theoretical and  current experimental constraints, are chosen in the type-I THDM with an exact alignment limit. The effect of individual  contributions from each type of one-loop diagram on the total cross-section is examined in detail. The dependence of  the cross-section on the center-of-mass energy is also presented at the various polarization configurations of the incoming  photons. Moreover, the regions m212122{}^2_{12}  -tan ß and mA -tan ß in the parameter space of the THDM are scanned for some  fixed values of other parameters. The box-type diagrams make a much bigger contribution to the cross-section than the  others at high energies. The total cross-section can be enhanced by a factor of two thanks to opposite-polarized photons  as well as threshold effects.
