单光子和双光子衰变对π^0介子中约束SU(3)胶子场参数和特性的估计

Estimates for parameters and characteristics of the confining SU(3)-gluonic field in π^0-meson from one- and two-photon decays

Yu. P. Goncharov

摘要:

本文在作者提出的禁闭机制的基础上,非微扰地计算了$π^0$介子的电形状因子。然后将后者应用于描述电磁衰变$π^0\to2γ$和$π^0\to e^+e^-γ$,从而得到了$π^0$ -介子中SU(3)-胶子场的参数估计.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 formfactor of $π^0$-meson is nonperturbatively calculated. The latter is then applied to describing electromagnetic decays $π^0\to2γ$ and $π^0\to e^+e^-γ$ which entails estimates for parameters of the confining SU(3)-gluonic field in $π^0$-meson. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field.
