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

TL;DR

This study investigates the hadronic decay widths of highly excited $2D$ $D_s$ resonances using the $^3P_0$ model, providing predictions for decay channels and their widths, which vary based on different particle assignments.

Contribution

It offers the first detailed calculation of decay widths of $2D$ $D_s$ resonances, highlighting how decay patterns depend on particle assignments and contributing to understanding their structure.

Findings

Decay widths to $D(2600)$ or $D(2750)$ can be large and vary with assignments.

Decay widths to $D^*_{s1}(2860)$, $D^*_{s3}(2860)$, or $D^*_{s1}(2700)$ are very small.

Decay widths are sensitive to the specific assignments of the involved resonances.

Abstract

Hadronic decays of the highly excited $2D$ $D_s$ resonances have been studied in the $^3P_0$ model. Widths of all possible hadronic decay channels of the $2D$ $D_s$ have been computed. $D^*_{s1}(2700)$, $D^*_{s1}(2860)$, $D^*_{s3}(2860)$, $D(2600)$ 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 $D^*_{s1}(2860)$, $D^*_{s3}(2860)$ or $D^*_{s1}(2700)$ are very small, and different in different assignments of $D^*_{s1}(2700)$.
