Extended Data Fig. 1: Correlation study comparison plots.
From: Joint neutrino oscillation analysis from the T2K and NOvA experiments
Posterior probability distributions of δCP (a), \({\sin }^{2}{\theta }_{23}\) (b), and \(\Delta {m}_{32}^{2}\) (c) and 1σ credible regions in \(\Delta {m}_{32}^{2}-{\sin }^{2}{\theta }_{23}\) (d), marginalized over both neutrino mass ordering hypotheses (‘Both MO’) from fits to pseudo-data simulated with the NuFit-like oscillation parameter values. The fits were run in three configurations while treating the systematic uncertainties with the largest impact on \({\sin }^{2}{\theta }_{23}\) (visible neutron energy and 2p2h C/O scale) as either 100% correlated (gray), uncorrelated (teal), or 100% anticorrelated (magenta). Overlaid with the corresponding 1σ (dark shaded areas, dashed) and 2σ (light shaded areas, dash-dotted) credible intervals.
