Estimate of elastic pole contributions to K+→π+γγ
Description
The elastic part of the amplitude for K+→π+γγ is considered and related to the finite self energy for K+ and π+ by means of Ward identities. The partial rate GAMMA(K+→π+γγ/GAMMA(K+→all) is estimated to be of the order 10-6 to 10-9 and cannot necessarily be neglected compared to other contributions. (Auth.)
