A dispersive approach to the CP conserving K → πℓ + ℓ − radiative decays
Abstract We reconsider the constraints on the form factors W +(s) and W S (s), describing the radiative decay modes K + → π + ℓ + ℓ − and K S → π 0 ℓ + ℓ − , associated with the general properties of analyticity and unitarity. Starting from the simple consideration of the asymptotic behaviours of th...
