Abstract

I briefly review the experimental observations concerning the charmed mesons DsJ(2317)D_{sJ}^*(2317), DsJ(2460)D_{sJ}(2460) and survey on some of the interpretations proposed in order to understand their nature. I present an analysis of their decay modes in the hypothesis that they can be identified with the scalar and axial vector sP=12+s_\ell^P={1 \over 2}^+ states of csˉc{\bar s} spectrum (Ds0D_{s0}^*, Ds1D_{s1}^\prime). The method is based on heavy quark symmetries and Vector Meson Dominance ansatz. Comparison with present data supports the interpretation.
