Semileptonic D(s) -meson decays in the light of recent data

2018

Inspired by recent improved measurements of charm semileptonic decays at BESIII, we study a large set of $D({D}_{s})$-meson semileptonic decays where the hadron in the final state is one of ${D}^{0}$, $\ensuremath{\rho}$, $\ensuremath{\omega}$, ${\ensuremath{\eta}}^{(\ensuremath{'})}$ in the case of ${D}^{+}$ decays, and ${D}^{0}$, $\ensuremath{\phi}$, ${K}^{0}$, ${K}^{*}(892{)}^{0}$, ${\ensuremath{\eta}}^{(\ensuremath{'})}$ in the case of ${D}_{s}^{+}$ decays. The required hadronic form factors are computed in the full kinematical range of momentum transfer by employing the covariant confined quark model developed by us. A detailed comparison of the form factors with those from other appro…
