An analysis of the Lattice QCD spectra for $D_{s0}^{\ast }(2317)$ and $D_{s1}^{\ast }(2460)$

Abstract

In this talk I present the results obtained using effective field theories in a finite volume from a reanalysis of lattice data on the $K{D}^{(\ast )}$ systems, where bound states of $KD$ and $K{D}^{\ast }$ are found and associated with the states $D_{s0}^{\ast }(2317)$ and $D_{s1}^{\ast }(2460)$, respectively. We confirm the presence of such states on the lattice data and determine the weight of the $KD$ channel in the wave function of $D_{s0}^{\ast }(2317)$ and that of $K{D}^{\ast }$ in the wave function of $D_{s1}^{\ast }(2460)$. Our results indicate a large meson-meson component in both cases.
