Abstract:
We study opportunities for future high-precision experiments in kaon physics using a high-intensity proton driver, which could be part of the front-end of a muon storage ring complex. We discuss in particular the rare decays KLπ0ννˉK_L\to\pi^0\nu\bar\nu, K+π+ννˉK^+\to\pi^+\nu\bar\nu, KLπ0e+eK_L\to\pi^0e^+e^-, and lepton-flavour violating modes such as KLμeK_L\to\mu e and KπμeK\to\pi\mu e. The outstanding physics potential and long-term interest of these modes is emphasized. We review status and prospects of current and planned experiments for the processes under consideration, and indicate possible improvements and strategies towards achieving the necessary higher sensitivity. Finally, we outline the machine requirements needed to perform these high-precision kaon experiments in the context of a muon storage ring facility.
