New data from the T2K neutrino oscillation experiment produce the most precise measurement of the neutrino mixing parameter theta_{23}. Using an off-axis neutrino beam with a peak energy of 0.6 GeV and a data set corresponding to 6.57 x 10^{20} protons on target, T2K has fit the energy-dependent nu_mu oscillation probability to determine oscillation parameters. Marginalizing over the values of other oscillation parameters yields sin^2 (theta_{23}) = 0.514 +0.055/-0.056 (0.511 +- 0.055), assuming normal (inverted) mass hierarchy. The best-fit mass-squared splitting for normal hierarchy is Delta m^2_{32} = (2.51 +- 0.10) x 10^{-3} eV^2/c^4 (inverted hierarchy: Delta m^2_{13} = (2.48 +- 0.10) x 10^{-3} eV^2/c^4). Adding a model of multinucleon interactions that affect neutrino energy reconstruction is found to produce only small biases in neutrino oscillation parameter extraction at current levels of statistical uncertainty.

  1. Effects of tau-neutrino detection on non-standard interactions at DUNE with a short discussion on the nature of neutrino mixing

    hep-ph 2025-03 unverdicted novelty 3.0

    Simulations show that tau neutrino appearance at DUNE improves sensitivity to NSI parameters especially ε_μτ, hierarchy, CP violation, octant, NSI phases, and PMNS unitarity constraints.

  2. Update on non-unitary mixing in the recent NO$\nu$A and T2K data

    hep-ph 2024-12 unverdicted novelty 3.0

    Analysis of recent NOνA and T2K data under non-unitary mixing yields tighter 90% limits on non-unitary parameters than prior data and indicates that α10 could reduce the 1σ tension between experiments for normal hierarchy.
