Study of form factors and branching ratios for $D\to S,Al\overline{{\nu }_l}$ with light-cone sum rules

Qi Huang, Yan-Jun Sun, Di Gao +3

We systematically study the semileptonic decay process of $D\to S,Al\overline{{\nu }_l}(l=e,\mu )$ by light-cone sum rules (LCSR) with chiral currents, calculate the form factors co…
