Description
In the type II seesaw model, there are seven physical Higgs states in mass basis and those can be categorized as charged Higgs bosons ($H^±$, $H^{±±}$) and the neutral Higgs bosons ($A^0$, $H^0$,$h^0$). At LHC, one of the primary ways to search for Higgs is via its decay to two photons. We studied the two-photon decay channel of SM-like component ($H^0$) of CP-even Higgs bosons and the pseudo scalar ($A^0$) in CP-odd bosons. For these loop-induced processes, we used computer-algebraic methods to generate Feynman diagrams and to obtain analytic expressions for $Γ(H^0→γγ)$ and $Γ(A^0→γγ)$. Some numerical results given by the analytic expression under the potential stability bounds condition for the $H^0→γγ$ process were compared with the SM.
