Kaon Decays beyond the Standard Model
Abstract
We review a new method in order to determine the parameter η of the Cabibbo-Kobayashi-Maskawa matrix from K→ μ+μ- decays, using interference effects in the time-dependent decay rate. Furthermore, we discuss a new precision relation for the phase-shift of the time-dependent oscillation. The new methodology enables the discovery potential of future time-dependent measurements of K→ μ+μ- decays for physics beyond the Standard Model.
