Incomplete GIM cancellation in\(K_L \to \bar \mu \mu \) decay

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Weak contributions to the decay\(K_L \to \bar \mu \mu \) are evaluated over the whole energy spectrum and it is found that terms which survive the GIM cancellation because of the size of the top quark mass are comparable in size to the ones previously kept. Corresponding bounds on the K-M mixing matrix elements are given.
