Triple Higgs boson production in a gamma gamma-collider at the future linear collider

In this study, triple Higgs boson production channels in a gamma gamma-collider are investigated in the context of the two-Higgs-doublet model (2HDM). This model has three neutral Higgs bosons (h(0)/H-0/A(0)) and two charged Higgs bosons (H-+/-). Between all the possible combinations of the triple Higgs bosons in the final state, only the following two scattering processes are probable at tree level: gamma gamma -> H(+)H(-)h(0) and gamma gamma -> (H+H-H0). These two processes are important to determine the triple Higgs self-couplings g(H+H-h0) and g(H)(+H-H0) in the 2HDM. The calculation is carried out for two scenarios, which are inspired by recent experimental and theoretical results. The cross-section of these processes is calculated and a comparison is made for these scenarios. The total convoluted cross-section with photon luminosity in an e(+)e(-)-collider is presented as a function of the center of mass energy.
