Higgs decay into a lepton pair and a photon revisited

Aliaksei Kachanovich, Ulrich Nierste, Ivan Nišandžić

We present new calculations of the differential decay rates for $H\to {\ell }^{+}{\ell }^{-}\gamma$ with $\ell =e$ or $\mu$ in the Standard Model. The branching fractions and forward-backward asymm…
