Search for Lepton Flavor Violation in K + Decays

The apparent lepton flavor conservation observed sofar in particle physics is conveniently accommodated inthe Standard Model if the neutrino masses are zero. Suchsymmetry can be broken by new physics at a higher en-ergy scale, such as Technicolor or Supersymmetry, or byneutrinos having Majorana masses. Extensive experi-mental efforts have been devoted to searches for lep-ton flavor violating kaon decays, K
