In this decade, there are huge efforts to explore B-meson decays, which provide an interesting playground for stringent tests of the Standard-Model description of the quark-flavour sector and the CP violation residing there. Thanks to the…
A rare decay $K_L \to \mu^+ \mu^- $ has been measured precisely, while a rare decay $K_S \to \mu^+ \mu^- $ will be observed by an upgrade of the LHCb experiment. Although both processes are almost CP-conserving decays, we point out that an…
