Abstract
We study the CP-conserving and -violating contributions to the decay of K →γνν̄ in the standard model. In our analysis, we use form factors for K→γ transitions calculated directly in the entire physical range of momentum transfer within the light front model. We find that the branching ratios for the CP-conserving and -violating parts are about 1.0 ×10 and 1.5×10 , respectively. © 2000 The American Physical Society.
