Masses and decay constants of the heavy tensor mesons with QCD sum rules
In this article, we calculate the contributions of the vacuum condensates up
to dimension-6 in the operator product expansion, study the masses and decay
constants of the heavy tensor mesons , ,
, using the QCD sum rules. The predicted masses
are in excellent agreement with the experimental data, while the ratios of the
decay constants
, where the exp denotes the experimental value.Comment: 13 pages, 13 figure
