Radiative and pionic transitions from the $D_{s1}(2460)$ to the $D_{s0}^{\ast }(2317)$

We estimate the partial widths for the radiative and pionic transitions from the $D_{s1}(2460)$ to the $D_{s0}(2317)$ in a molecule scenario, in which the $D_{s1}(2460)$ and $D_{s0}^{\ast }(2317)$ are considered as hadronic molecule states of $DK$ and $D^{\ast }K$, respectively. The partial widths for the $D_{s1}(2460)\to D_{s0}^{\ast }(2317){\pi }^0$ and $D_{s1}(2460) \to D_{s0}^\ast(2317) \gamma$areevaluatedtobeabout$0.19 \sim 0.22$keVand$3.0 \sim 3.1$keV,respectively\mathrm{.}Inaddition,theratioofthe$D_{s1}(2460) \to D_{s0}(2317) \gamma$and$D_{s1}(2460) \to D_{s}^\ast \pi^0$ is estimated to be about $(6.6\sim 10.6)\times {10}^{-2}$, which is safely under the measured upper limit.
