η-η混合的理论确定

A theoretical determination of the eta-eta' mixing

C. Degrande, J. -M. Gerard

摘要:

在p^2的首阶,系统的大N_c限制提供了约-27度的最佳η-η '混合角。在此框架下,与数据的协议可以达到约20%的高阶校正。

英文摘要:

The systematic large N_c limit within chiral perturbation provides an optimal eta-eta' mixing angle of about -27 degrees at leading order in p^2. In this frame, agreement with the data can be reached with higher order corrections of about 20%.
