Abstract
We perform a chiral one-loop calculation of the unitarity corrections to th e processes K+ --> pi(+) gamma l(+) l(-) up to O(E degrees), taking into ac count pi(+) pi(-) intermediate states. Branching ratios and differential br anching ratios are computed and presented to demonstrate the importance of the above corrections. [S0556-2821(99)06209-8].
