Description
In this article, we calculate the contributions of the vacuum condensates up to dimension-6 in the operator product expansion and study the masses and decay constants of the heavy tensor mesons D2*(2460), Ds2*(2573), B2*(5747), Bs2*(5840) using the QCD sum rules. The predicted masses are in excellent agreement with the experimental data, while the ratios of the decay constants (fDs2*)/(fD2*) ∼ (fBs2*)/(fB2*) ∼ (fDs)/(fD) vertical stroke exp, where the exp denotes the experimental value.
