Higgs boson decay into a lepton pair and a photon revisited
Higgs boson decay into a lepton pair and a photon revisited
We present new calculations of the differential decay rates for $H\ensuremath{\rightarrow}{\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}\ensuremath{\gamma}$ with $\ensuremath{\ell}=e$ or $\ensuremath{\mu}$ in the Standard Model. The branching fractions and forward-backward asymmetries, defined in terms of the flight direction of the photon relative to the lepton momenta, depend on the cuts on energies and invariant masses of …
