Strong decay of the heavy tensor mesons with QCD sum rules

Abstract

In the article, we calculate the hadronic coupling constants $G_{D_2^*Dπ}$, $G_{D_{s2}^*DK}$, $G_{B_2^*Bπ}$, $G_{B_{s2}^*BK}$ with the three-point QCD sum rules, then study the two body strong decays $D_2^*(2460)\to Dπ$, $D_{s2}^*(2573)\to DK$, $B_2^*(5741)\to Bπ$, $B_{s2}^*(5840)\to BK$, and make predictions to be confronted with the experimental data in the future.
