TL;DR

This paper investigates the newly observed $D_{s1}^*(2860)$ and $D_{s3}^*(2860)$ resonances, proposing they are $1^3D_1$ and $1^3D_3$ charmed-strange mesons, and predicts their decay modes and related spin partners for future experimental verification.

Contribution

Predicted decay modes and missing $1D(2^-)$ and $1D'(2^-)$ mesons

Abstract

Newly observed two charmed-strange resonances, $D_{s1}^*(2860)$ and $D_{s3}^*(2860)$, are investigated by calculating their Okubo-Zweig-Iizuka allowed strong decays, which shows that they are suitable candidates for the $1^3D_1$ and $1^3D_3$ states in the charmed-strange meson family. Our study also predicts other main decay modes of $D_{s1}^*(2860)$ and $D_{s3}^*(2860)$, which can be accessible at the future experiment. In addition, the decay behaviors of the spin partners of $D_{s1}^*(2860)$ and $D_{s3}^*(2860)$, i.e., $1D(2^-)$ and $1D^\prime(2^-)$, are predicted in this work, which are still missing at present. Experimental search for the missing $1D(2^-)$ and $1D^\prime(2^-)$ charmed-strange mesons is an intriguing and challenging task for further experiment.
