Measurement of the Neutrino Mixing Angle θ_{23} in NOvA

10.04.2017 by Kaido Reivelt

Author(s): P. Adamson et al. (NOvA Collaboration)

A pair of long-baseline neutrino oscillation experiments, T2K and NOvA, probe whether μ and τ neutrinos maximally mix, as experiments have heretofore shown. T2K’s data is consistent with maximal mixing, but NOvA’s data disfavors it.
