Abstract
We present new , , , and oscillation measurements by the NOvA experiment, with a 50% increase in neutrino-mode beam exposure over the previously reported results. The additional data, combined with previously published neutrino and antineutrino data, are all analyzed using improved techniques and simulations. A joint fit to the , , , and candidate samples within the 3-flavor neutrino oscillation framework continues to yield a best-fit point in the normal mass ordering and the upper octant of the mixing angle, with and . The data disfavor combinations of oscillation parameters that give rise to a large asymmetry in the rates of and appearance. This includes values of the charge parity symmetry (CP) violating phase in the vicinity of which are excluded by for the inverted mass ordering, and values around in the normal ordering which are disfavored at confidence.

Long-Baseline Neutrino Experiments March On
Published 3 August 2022
Long-baseline neutrino experiments are paving the way for the solution of two outstanding puzzles in neutrino physics—mass ordering and charge-parity violation.
