Properties of $D_{s2}^{*}(2573)$ charmed-strange tensor meson

The mass and current coupling constant of the $D_{s2}^{*}(2573)$ charmed-strange meson is calculated in the framework of the two-point QCD sum rule approach. Although the quantum numbers of this meson are not exactly known, its width and decay modes are consistent with $I(J^P)=0(2^{+})$, which we consider to write the interpolating current used in our calculations. Replacing the light strange quark with the up or down quark, we also compare the results with those of the $D_2^{*}$ charmed tensor meson and estimate the order of SU(3) flavor symmetry violation.
