Lattice calculation of the $D_s$ meson radiative form factors over the full kinematical range

R. Frezzotti, G. Gagliardi, V. Lubicz +6

We compute the structure-dependent axial and vector form factors for the radiative leptonic decays $D_s\to \ell {\nu }_{\ell }\gamma$, where $\ell$ is a charged lepton, as functions of the energ…
