NON-STANDARD-MODEL CP VIOLATION IN K-MU-3 DECAYS AS A METHOD OF PROBING FOR NEW PHYSICS

The transverse polarization of the muon (P-mu perpendicular-to) in the decay K+ --> pi-o-mu + nu-mu is a very useful tool for studying CP violation because a detectable nonzero P-mu perpendicular-to can only arise from physics beyond the standard model. Further, P-mu perpendicular-to is interesting because it probes a different region of parameter space than many other CP-violating observables. To help justify an experimental search, we present three models which give P-mu perpendicular-to greater-than-or-similar-to 10(-3) and which are not contradicted by other experimental data. We also comment on K --> pi-mu-mu decays.
