Description

Ksub(L) → 2 γ and Ksub(L) → π+π-γ weak radiative decays in the Weinberg-Salam model for weak interactions and in the framework of asymptotic-free gradient theory for strong interactions have been considered. The problem of decay calculations at small and great distances is discussed. It has been shown that contributions of great distances mostly are the cause of the Ksub(L) meson weak radiative decays. A ratio relating the contributions and therefore, decay amplitudes one with another through certain constants are proved by the PCAC anomaly theory. An effective Hamiltonian determining Ksub(L) →π+π-γ decay at small distances has been obtained, in this case strong interaction effects are taken account of. The Hamiltonian matrix elements and a small distance contribution into Ksub(L) → π+π-γ are calculated. The derived ratio between decay amplitudes is verified experimentally
