Strong coupling constants of charmed and bottom mesons with light vector mesons in QCD sum rules

Abstract

We estimate the strong coupling constants of charmed and bottom mesons $D_{(s)}^{\ast }$, $D_{(s)1}$, $B_{(s)}^{\ast }$, and $B_{(s)1}$ with light vector mesons $\rho$, $\omega$, $K^{\ast }$, and $\varphi$ within the framework of light-cone QCD sum rules. We compare our estimations to the ones predicted by other approaches.
