摘要:

用QCD求和规则方法计算了基态奇异张量介子$K_2^*(1430)$与$I(J^P)=1/2(2^+)$的质量和衰变常数。计算结果与实验数据吻合较好。发现SU(3)对称性破缺效应约占衰变常数的$20^0/_0$。

英文摘要:

The mass and decay constant of the ground state strange tensor meson $K_2^*(1430)$ with $I(J^P)=1/2(2^+)$ is calculated using the QCD sum rules method. The results are consistent with the experimental data. It is found that SU(3) symmetry breaking effect constitutes about $20^0/_0$ of the decay constant.
