µ → eγ AND µ → 3e PROCESSES WITH POLARIZED MUON AND SUPERSYMMETRIC GRAND UNIFIED THEORIES a

Lepton flavor violating processes μ → eγ and μ → 3e with polarized muons are studied in the supersymmetric grand unified theory (SUSY GUT). As a result of a detailed numerical calculation, it is shown that the Pand T-odd asymmetries defined with the help of the muon polarization and the ratio of two branching fractions make a good contrast between the SU(5) and SO(10) SUSY GUT. These observable...

CP violation in the μ → 3 e process and supersymmetric grand unified theory

A triple vector correlation in the μ → eee decay with polarized muons is investigated as a probe to CP violating coupling constants in supersymmetric models. A sizable triple correlation can be induced due to a complex phase in the supersymmetric soft-breaking terms in the SU(5) grand unified theory. Correlation with the electric dipole moment of the electron is investigated and it is shown tha...

We have observed the rare decay K+→π+μ+μ− and measured the branching ratio Γ(K+→π+μ+μ−)/Γ(K+→all) = (5.0± 0.4stat ± 0.7syst ± 0.6th)× 10−8. We compare this result with predictions from chiral perturbation theory and estimates based on the decay K+→π+e+e−. PACS numbers: 13.20.Eb, 12.39.Fe Typeset using REVTEX
