Triple Higgs Boson Production In A Γγ-Collider At The Future Linear Collider, Nasuf Sönmez

Turkish Journal of Physics

In this study, triple Higgs boson production channels in a γγ-collider are investigated in the context of the two-Higgs-doublet model (2HDM). This model has three neutral Higgs bosons (h0/H0/A0 ) 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: γγ → H+H-h0 and γγ → H+H-H0. These two processes are important to determine the triple Higgs self-couplings gH+H-h0 and gH+H-H0 in the 2HDM. The calculation is carried out for two scenarios, which are inspired by recent experimental and theoretical …
