Description

In this talk I present the formalism we have used to analyze Lattice data on two meson systems by means of effective field theories. In particular I present the results obtained from a reanalysis of the lattice data on the KD(∗) systems, where the states D∗s0(2317) and D∗s1(2460) are found as bound states of KD and KD∗, respectively. We confirm the presence of such states in the lattice data and determine the contribution 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 findings indicate a large meson–meson component in the two cases. (author)
