$D_{s1}^{\ast }(2860)$ and $D_{s3}^{\ast }(2860)$: Candidates for $1D$ charmed-strange mesons

Abstract

Newly observed two charmed-strange resonances, $D_{s1}^{\ast }(2860)$ and $D_{s3}^{\ast }(2860)$, are investigated by calculating their Okubo-Zweig-Iizuka allowed strong decays, which shows that they are suitable candidates for the $1^3{D}_1$ and $1^3{D}_3$ states in the charmed-strange meson family. Our study also predicts other main decay modes of $D_{s1}^{\ast }(2860)$ and $D_{s3}^{\ast }(2860)$, which can be accessible at the future experiment. In addition, the decay behaviors of the spin partners of $D_{s1}^{\ast }(2860)$ and $D_{s3}^{\ast }(2860)$, 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.
