Strong coupling constants and radiative decays of the heavy tensor mesons

In this article, we analyze tensor-vector-pseudoscalar(TVP) type of vertices $D_{2}^{*+}D^{+}rho$, $D_{2}^{*0}D^{0}rho$, $D_{2}^{*+}D^{+}omega$, $D_{2}^{*0}D^{0}omega$, $B_{2}^{*+}B^{+}rho$, $B_{2}^{*0}B^{0}rho$, $B_{2}^{*+}B^{+}omega$, $B_{2}^{*0}B^{0}omega$, $B_{s2}^{*}B_{s}phi$ and $D_{s2}^{*}D_{s}phi$, in the frame work of three point QCD sum rules. According to these analysis, we calculate their strong form factors which are used to fit into analytical functions of $Q^{2}$. Then, we obtain the strong coupling constants by extrapolating these strong form factors into deep time-like regions. As an application of this work, the coupling constants for radiative decays of these heavy tensor mesons are also calculated at the point of $Q^{2}=0$. With these coupling constants, we finally calculate the radiative decay widths of these tensor mesons.
