摘要:

在推广的$U(3)\times U(3)$手性Nambu-Jona-Lasinio模型的框架下计算了$τ\to a_{1} πν_τ$、$τ\to K_{1} πν_τ$和$τ\to K_{1} K ν_τ$衰变的支化分数.目前还没有这些衰变的实验数据,因此所获得的结果被认为是预测。这些结果进行了比较,其他作者的理论结果。

英文摘要:

The branching fractions of the decays $τ\to a_{1} πν_τ$, $τ\to K_{1} πν_τ$ and $τ\to K_{1} K ν_τ$ are calculated in the framework of the extended $U(3)\times U(3)$ chiral Nambu--Jona-Lasinio model. There are no experimental data for these decays in the present time, thus the obtained results are considered as predictions. The comparison of these results to the theoretical results of other authors is carried out.
