Their widths are small because they decay dominantly through isospin-breaking hadronic channels $D_{s0}^*(2317)^+\\to D_s^+\\pi^0$ and $D_{s1}(2460)^+\\to D_s^{*+}\\pi^0$. The $D_{s1}(2460)$ can also decay into the hadronic final states $D_s^+\\pi\\pi$, conserving isospin. In that case there is, however, a strong suppression from phase space. We study the transition $D_{s1}(2460)^+\\to D_s^+\\pi^+\\pi^-$ in the scenario that the $D_{s1}(2460)$ is a $D^*K$ hadronic molecule.
