Radiative transitions ofDsJ*(2317)andDsJ(2460)

We study radiative decays of $D_{sJ}^{*}(2317)$ and $D_{sJ}(2460)$ using light-cone QCD sum rules. In particular, we consider the decay modes $D_{sJ}^{*}(2317)\to D_s^{*}\gamma$ and $D_{sJ}(2460)\to D_s^{(*)}\gamma ,D_{sJ}^{*}(2317)\gamma$ and evaluate the hadronic parameters in the transition amplitudes analyzing correlation functions of scalar, pseudoscalar, vector, and axial-vector $\overline{c}s$ currents. In the case of $D_{sJ}^{*}(2317)\to D_s^{*}\gamma$ we also consider determinations based on two different correlation functions in heavy quark effective theory (HQET), in order to estimate the finite charm-quark mass effects. The mode $D_{sJ}(2460)\to D_s\gamma$ turns out to have the largest decay rate among the radiative $D_{sJ}(2460)$ channels, as experimentally observed, a result thus favoring the interpretation of $D_{sJ}$ states as ordinary $\overline{c}s$ mesons.
