On the two-loop BSM corrections to $$h\longrightarrow \gamma \gamma $$ h ⟶ γ γ in a triplet extension of the SM

Abstract We compute the two-loop BSM contributions to the $$h\longrightarrow \gamma \gamma $$ h ⟶ γ γ decay width in the SM extended with a real triplet of SU(2). We consider scenarios in which the neutral components of doublet and triplet do not mix, so that the lighter neutral scalar h has (at lea...
