KOFFEE: Kaon Observables at Future Fermilab Experimental Extensions

The rare decays $K^+\to\pi^+\nu\bar\nu$ and $K_L\to\pi^0\nu\bar\nu$ are among the most precisely predicted flavor observables, enabling determinations of the CKM matrix and its CP-violating phase, as well as providing sensitivity to new physics at scales far beyond the reach of colliders. We propose a dedicated rare-ka...
