Major advances spanning several orders of magnitude in sensitivity are anticipated in the current round of experiments dealing with rare kaon decays. Observations of allowed processes, like [Formula: see text] and [Formula: see text], shed light on detailed aspects of the standard model.

Rare decay experiments have made significant advances in the last several years. Limits on lepton number violating decays of kaons have been tightened. Large samples of strangeness changing neutral current kaon decays have been collected. For several suppressed processes, discovery windows for new physics have been substantially narrowed. Opportunities

A review is given of searches for rare muon decay modes. Recent experiments have substantially reduced the upper limits on the branching ratios of the muon‐number violating decays μ→eγ, μ→eγγ, and μ→eee. MEGA, an experiment to search for μ→eγ with a sensitivity of a few parts in 1013, is underway at LAMPF.

We study the rare kaon decays of [Formula: see text] and [Formula: see text]. In the standard mode, we find that the CP conserving and violating contributions to the branching ratios of [Formula: see text] are about 4.4 (1.0)× 10-13 and 1.0 (0.15)× 10-14, respectively.

In the rush to explore the B system, one should not ignore the potential of rare K decays. The charged and neutral FCNC K {yields} {pi}{nu}{bar {mu}} decays are theoretically very clean, on a par with B {yields} {psi}K{sub S}, which measures {beta}, and much less problematic than B {yields} {pi}{pi} and B{sub s} {yields} K{sup +}K{sup -} or B{sub s ...

At the end of 1994 the four LEP experiments (ALEPH, DELPHI, L3 and OPAL) have each collected approximately 3.5 million hadronic Z0 decays. These large samples allow to search for rare decays of the Z0 boson at the level of 10−5 or better. A review of some of these searches is presented.
