Abstract: (APS)

The transverse polarization of the muon (Pμ⊥) in the decay K+→π0μ+νμ is a very useful tool for studying CP violation because a detectable nonzero Pμ⊥ can only arise from physics beyond the standard model. Further, Pμ⊥ 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 Pμ⊥≳10−3 and which are not contradicted by other experimental data. We also comment on K→πμμ decays.
