Abstract
The LHCb Collaboration has recently reported the observation for the first time of a spin-$3$ resonance in the heavy quark sector. They have shown that the $\bar{D}^{0}K^{-}$ structure seen in the $B_{s}^{0}\to \bar{D}^{0}K^{-}\pi^{+}$ reaction and with invariant mass $2.86\,{\rm GeV}$ is an admixture of a spin-$1$ and a spin-$3$ resonances. Motivated by the good agreement between our theoretical predictions some time ago and the properties extracted from the experiment of the $D_{s1}^{\ast}(2860)$ and $D_{s3}^{\ast}(2860)$ states, we perform an extension of the study of the strong decay properties of the $D_{sJ}^{\ast}(2860)$ and present the same analysis for t...
