The effect of an anomalous Higgs trilinear self-coupling on the $$h \rightarrow \gamma \, Z$$ h→γZ decay
Abstract We compute the two-loop effects induced by an anomalous Higgs trilinear self-coupling in the partial decay width $$\Gamma (h \rightarrow \gamma Z)$$ Γ(h→γZ) . The computation is performed using the anomalous coupling approach, working in the unitary gauge, and in a theory in which the anoma...
