摘要

\(V \rightarrow K(\pi ) l \bar{\nu }_l \)的衰减宽度在Nambu-Jona-Lasinio模型中计算，其中\(V=K^*, \rho , \omega , \phi \)和\(l=\mu , e\)。结果是在不引入任意参数的情况下，使用先前固定的模型参数得到的。由于缺乏实验数据，所得结果被认为是预测结果。

Weak Semileptonic Decays of Vector Mesons in the NJL Model

The decay widths of \(V \rightarrow K(\pi ) l \bar{\nu }_l \) are calculated within the Nambu–Jona-Lasinio model, where \(V=K^*, \rho , \omega , \phi \) and \(l=\mu , e\). The results are obtained using the previously fixed model parameters without introducing any arbitrary parameters. The obtained results are considered as predictions due to the absence of experimental data.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
