Anomalous Radiative Decay of Heavy Higgs Boson

Abstract

The radiative decay width of a heavy Higgs boson $H\to W^{+}{W}^{-}\gamma$ for a {\it hard} photon is calculated in the Standard Model and its extension with anomalous $\gamma WW$ couplings. Its dependence on the Higgs mass, the two unknown anomalous couplings, and the photon energy cutoff are studied in detail. We show that this radiative decay of a heavy Higgs is not very sensitive to a wide range of the anomalous couplings compared to the Standard Model result.
