Loop induced (WH -/+)-H-+/- associated production via photon-photon collisions in the two-Higgs-doublet model and the minimal supersymmetric standardmodel - art. no. 055005

We study the loop induced production of a charged Higgs boson associated wi th a W boson via photon-photon collisions at linear colliders (LC). The inv estigation is carried out under the two-Higgs-doublet model (THDM) and the minimal supersymmetric model (MSSM) using the full on-mass-shell renormaliz ation scheme. The numerical analysis of their production rates is presented with some typical parameter sets. The results show that the total cross se ctions in the frame of the MSSM at linear colliders (LC) can reach 0.1 fb q uantitatively. The contributions from the supersymmetric sector can lead to an order-of-magnitude enhancement of the cross section in some parameter s pace. We conclude that the associated W+/-H+/- production rate in the photo n-photon collision mode is comparable to that in the e(+)e(-) collision mod e.
