Radiative corrections to the ${\eta }^{(\prime )}$ Dalitz decays

Tomas Husek, Karol Kampf, Stefan Leupold +1

We provide the complete set of radiative corrections to the Dalitz decays ${\eta }^{(\prime )}\to {\ell }^{+}{\ell }^{-}\gamma$ beyond the soft-photon approximation, i.e. over the whole range of the Dal…
