Rare kaon decays

The subject of rare and ultra-rare kaons decays is very active at this time with 8 experiments from 4 labs reporting new results recently and 6 new experiments recently approved. The physics topics under study include flavor changing neutral currents (FCNC), measurements of direct and indirect CP violation and searches for lepton flavor violation (LFV). These measurements are all characterized by very high sensitivities, studying modes with branching ratios in the 10-7--10-12 range with single event sensitivities approaching 10-12. This is a region of sensitivity beyond the reach of charm and B experiment, at least for now. The development of beams with fluxes well above 1MHz of kaon decays enable these experiments. In this paper the author covers some of the important new results and the goals for the new experiments
