摘要: In this paper we study the effects of $s\to d + 2{gluon}$ on $K_L \to \gamma\gamma$ in Standard Model. We find that interaction can induce new sizeable SU(3) and U(3) nonet breaking - \eta, \eta'$ transitions therefore $K_L\to due to large matrix elements $ from QCD anomaly. These play an important role explaining observed value. also contribution $\Delta m_{K_L-K_S}$.
