Description
The T2K and NOvA experiments study neutrino oscillations using predominantly muon and antimuon flavor accelerator neutrino beams from J-PARC in Japan and Fermilab in the United States, respectively. Observations of muon and electron neutrino interactions in the experiments' Far Detectors, at baselines of hundreds of km from the neutrino source, permit inferences on parameters of the PMNS matrix, as well as the neutrino mass splittings and ordering. Subsequent to the first joint analysis of the two experiments' data, published in 2025, the collaborations continue to refine the analysis. This poster will discuss recent advances in the technique, such as improvements in the technical interface between the collaborations' software tools and additional demonstrations of the analysis's robustness to potentially shared systematic uncertainties, as well as the impact of additional recently collected data that was not included in the previous measurements.
