Resumo
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, jεeτj, and phase,
ðδCP þ δeτÞ, using a 30-bin likelihood fit.
