Hadronic decays of the highly excited $2D$ $D_s$ resonances

Abstract

Hadronic decays of the highly excited $2D$ $D_s$ resonances have been studied in the ${}^3{P}_0$ model. Widths of all possible hadronic decay channels of the $2D$ $D_s$ have been computed. $D_{s1}^{\ast }(2700)$, $D_{s1}^{\ast }(2860)$, $D_{s3}^{\ast }(2860)$, $D(2600)$ and $D(2750)$ can be produced from hadronic decays of the $2D$ $D_s$, and relevant hadronic decay widths have been particularly paid attention to. The hadronic decay widths of $2D$ $D_s$ to $D(2600)$ or $D(2750)$ may be large, and the numerical results are different in different assignments of $D(2600)$ and $D(2750)$. The hadronic decay widths of $2D$ $D_s$ to $D_{s1}^{\ast }(2860)$, $D_{s3}^{\ast }(2860)$ or $D_{s1}^{\ast }(2700)$ are very small, and different in different assignments of $D_{s1}^{\ast }(2700)$.
