A search for flavor-changing non-standard neutrino interactions using ${\nu }_e$ appearance in MINOS

Abstract

We report new constraints on flavor-changing non-standard neutrino interactions from the MINOS long-baseline experiment using ${\nu }_e$ and ${\bar{\nu }}_e$ appearance candidate events from predominantly ${\nu }_{\mu }$ and ${\bar{\nu }}_{\mu }$ beams. We used a statistical selection algorithm to separate ${\nu }_e$ 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 non-standard interaction matter effect, $|{\epsilon }_{e\tau }|$, and phase, $({\delta }_{CP}+{\delta }_{e\tau })$, using a thirty-bin likelihood fit.
