用双光子衰变估计$η$介子中SU(3)-胶子场的参数和特性

Estimates for parameters and characteristics of the confining SU(3)-gluonic field in $η$-meson from two-photon decay

Yu. P. Goncharov

摘要:

在作者提出的约束机制的基础上,非微扰地计算了$η$介子的电形状因子。然后应用后者描述电磁衰变$η\to2γ$,从而估计了$η$ -介子中SU(3)-胶子场的参数.对于上述场,也给出了相应的胶子浓度、电色场和磁色场强度的估计。

英文摘要:

On the basis of the confinement mechanism earlier proposed by author, the electric form factor of $η$-meson is nonperturbatively calculated. The latter is then applied to describe electromagnetic decay $η\to2γ$ which entails estimates for parameters of the confining SU(3)-gluonic field in $η$-meson. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field.
