摘要：
We look for possible signatures of multiquark structures in the heavy-light meson spectra. The controversial D-s0*(2317) and D-s1*(2460) states are properly described if conso sidered as a mixture of conventional P-wave qq and four-quark components. The recently discovered D-sJ(2860) appears as the orthogonal partner of the D-s0*(2317). Similar structures are predicted in the B-s sector. We also consider the possible existence of isolated I = 1 four-quark resonances and we argue that their existence can disentangle the Gamma(nS) -> Gamma(mS)pi pi decay puzzle.
