Strong and Electromagnetic Decays of The $D$-wave Heavy Mesons

Peng-Zhi Huang, Liang Zhang, Shi-Lin Zhu

We calculate the $\pi$, $\rho$, $\omega$, and $\gamma$ coupling constants between the heavy meson doublets $(1^{-},2^{-})$ and (0^-,1^-)/(0^+,1^+) within the framework of the light-cone QCD sum rule…
