Abstract

We propose an unprecedented detection of reactor ν_e → ν_μ and ν_e → ν_τ oscillations by using elastic antineutrino-electron scattering processes ν_α+ e^- → ν_α+ e^- (for α= e, μ, τ), among which the ν_e events can be singled out by accurately measuring the ν_e flux via the inverse beta decay ν_e + p → e⁺ + n. A proof-of-concept study shows that such measurements will not only be able to test the conservation of probability for reactor antineutrino oscillations, but also offer a new possibility to probe leptonic CP violation at the one-loop level.
