Abstract
We report new constraints on flavor-changing nonstandard neutrino interactions from the MINOS long-baseline experiment using νe and νe appearance candidate events from predominantly νμ and νμ beams. We used a statistical selection algorithm to separate νe 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, | μeτ|, and phase, (δCP+δeτ), using a 30-bin likelihood fit.
