Long baseline neutrino physics with a muon storage ring neutrino source

We examine the physics capabilities of known flavor neutrino beams from intense muon sources. We find that long-baseline neutrino experiments based on such beams can provide precise measurements of neutrino oscillation mass and mixing parameters. Furthermore, they can test whether the dominant atmospheric neutrino oscillations are ν_μ→ν_τ and/or ν_μ→ν_s, determine the ν_μ→ν_e content of atmospheric neutrino oscillations, and measure ν_e→ν_τ appearance. Depending on the oscillation parameters, they may be able to detect Earth matter and CP violation effects and to determine the ordering of some of the mass eigenstates.
