Abstract

We examine the sensitivity to ν_μ--> ν_e of a conceptual neutrino experiment that involves a neutrino superbeam, a Megaton-scale water Cherekov detector, and a "magic" baseline ~7300 km. With realistic beam intensity and exposure time, the mixing parameter sin² 2θ₁₃ and the sign of "atmospheric" mass-squared difference may be unambiguously probed down to sin² 22θ₁₃ values below 10^-3.
