Özet
In
the framework of two Higgs doublet model (2HDM), the associated production of
neutral Higgs boson with a γ via an e-e+ collision is investigated at the
one-loop level. On the other hand, the process at the tree level is suppressed
by the electron mass. For numerical evaluation, a few benchmark points, which
are compatible with theoretical and current experimental constraints, are
chosen in the type-I of 2HDM. The dependence of the cross section on the
center-of-mass energy is also presented at the various polarization configurations
of the initial beams. It is shown that depending selected BPs, there is a
deviation from the predictions of SM where the production rate is significantly
enhanced. The cross section is enhanced up to about four times by the completely polarized right-handed
positron and left-handed electron. At √s = 250 GeV, s2HDM(e-Le+R→h0γ) reaches to a value of 0.27 fb.
