Radiative Higgs Boson Decays H -> f fbar gamma

Abstract

Higgs boson radiative decays of the form $H\to f\bar{f}\gamma$ are calculated in the Standard Model using the complete one-loop expressions for the decay amplitudes. Contributions to the radiative width from leptons and light quarks are given. We also present $e\bar{e}$ invariant mass distributions for $H\to e\bar{e}\gamma$, which illustrate the importance of the photon pole contribution and the effects of the box diagrams.
