摘要: The decay width of the process {eta}{yields}{pi}{sup 0}{gamma}{gamma} is calculated in framework Nambu-Jona-Lasinio model. momentum dependence quark loops taken into account. Three types diagrams are considered: box, scalar (a{sub 0}) and vector ({rho},{omega}) pole diagrams. obtained estimations satisfactory agreement with recent experimental data.
