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 KD^(*) systems, where bound states of KD and KD^* are found and associated with the states D^*_s0(2317) and D^*_s1(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(2317) and that of KD^* in the wave function of D^*_s1(2460). Our results indicate a large meson-meson component in both cases.
