M. K. Volkov, E. A. Kuraev, Yu. M. Bystritskiy

摘要:

计算了正负电子束碰撞中标量介子$f_0(980)$、$a_0(980)$和$σ(600)$的产生截面。在Nambu-Jona-Lasinio模型的框架下,标量介子的双光子衰变被使用。考虑了夸克和介子环。

英文摘要:

The cross sections of the scalar meson $f_0(980)$, $a_0(980)$ and $σ(600)$ production in collision of electron and positron beams were calculated. The two-photon decays of the scalar mesons, obtained in the framework of the Nambu-Jona-Lasinio model, were used. The quark and meson loops were taken into account.
