h \gamma \gamma Coupling in Higgs Triplet Model

Abstract

We investigate Higgs boson decay into two photons in the type-II seesaw model. The rate of $h\to \gamma\gamma$ gets suppressed/enhanced in this model compared to the Standard Model (SM) due to the presence of the singly and doubly charged Higgs $H^\pm$ and $H^{\pm\pm}$.Comment: Latex, 7 pages, 2 Figures.
