Abstract

We determine the quark mass dependence—light and heavy—of the Ds0*(2317) and Ds1(2460) properties, such as, mass, coupling to D(*)K, scattering lengths and compositeness, from a global analysis of D(*)K energy levels from LQCD. In particular, we analyze the HSC energy levels for DK scattering in I=0 for different boosts and two pion masses. The formalism is based in the local hidden-gauge interaction of Weinberg-Tomozawa type which respects both chiral and heavy quark spin symmetries, supplemented by a term that takes into account the D(*)K coupling to a bare cs¯ component. The isospin violating decay of the Ds0*(2317)→Ds+π0 is also evaluated.
