Search for flavor-changing nonstandard neutrino interactions using ν_e appearance in MINOS


We report new constraints on flavor-changing nonstandard neutrino interactions from the MINOS long-baseline experiment using ν_e and ν_e appearance candidate events from predominantly ν_μ and ν_μ beams. We used a statistical selection algorithm to separate ν_e candidates from background events, enabling an analysis of the combined MINOS neutrino and antineutrino data. We observe no deviations from standard neutrino mixing, and thus place constraints on the nonstandard interaction matter effect, |ϵ_(eτ)|, and phase, (δ_(CP)+δ_(eτ)), using a 30-bin likelihood fit.
