Semileptonic Decays of $D\to \ddot{I}l^{+}\hat{I}½$ and $D_{(s)}\to K^{\ast }{l}^{+}\hat{I}½$ from Light-Cone Sum Rules

Wang Lin, Xiao-En Huang, Shan Cheng +1

We investigate the semileptonic decays of charmed mesons to light vector mesons within the framework of light-cone sum rules. Our calculation is performed at leading order in QCD c…
