Abstract

We review a new method in order to determine the parameter ηˉ\bar{\eta} of the Cabibbo-Kobayashi-Maskawa matrix from Kμ+μK\rightarrow \mu^+\mu^- 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 Kμ+μK\rightarrow \mu^+\mu^- decays for physics beyond the Standard Model.
