Short-baseline neutrino oscillations at a neutrino factory

Within the framework of three-neutrino and four-neutrino scenarios that can describe the results of the LSND experiment, we consider the capabilities of short-baseline neutrino oscillation experiments at a neutrino factory. We find that, when short-baseline (L100 km) neutrino factory measurements are used together with other accelerator-based oscillation results, the complete three-neutrino parameter space can best be determined by measuring the rate of νₑ→ν_τ oscillations, and measuring CP violation with either νₑ→ν_μ or ν_μ→ν_τ oscillations (including the corresponding antineutrino channels). With measurements of CP violation in both νₑ→ν_μ and ν_μ→ν_τ it may be possible to distinguish between the three- and four-neutrino cases.
