Quark mass dependence of the $D_{s0}^{\ast }(2317)$ and $D_{s1}(2460)$ resonances

F. Gil-Domínguez, R. Molina

We determine the quark mass dependence - light and heavy - of the $D_{s0}^{\ast }(2317)$ and $D_{s1}(2460)$ properties, such as, mass, coupling to $DK$, scattering lengths and compositen…
