Resumo

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. (AU)
