论文摘要
在目前的工作中，在nambu-jona-lasinio模型的框架中估计了向量$ω（782）$和$ ϕ（1020）$ MESON的混合角度。衰减$ ϕ \至π^{0}γ$被认为是确定此角度的基本过程。将获得的值与其他作者的结果进行了比较。此外，衰减$ ϕ \至3π$的宽度以及该过程的横截面$ e^{+} e^{ - } \toπ^{0} ϕ $是通过使用此角度来计算的。
In the present work, the mixing angle of the vector $ω(782)$ and $ϕ(1020)$ mesons is estimated in the framework of Nambu--Jona-Lasinio model. The decay $ϕ\to π^{0} γ$ is considered as a basic process to determine this angle. The obtained value is compared with the results of the other authors. Besides, the width of the decay $ϕ\to 3π$ and the cross-section of the process $e^{+}e^{-} \to π^{0} ϕ$ are calculated by using this angle.
