Joint neutrino oscillation analysis from the T2K and NOvA experiments

NOvA, T2K Collaborations, : +597

The landmark discovery that neutrinos have mass and can change type (or "flavor") as they propagate -- a process called neutrino oscillation -- has opened up a rich array of theore…

Measurement of muon neutrino induced charged current interactions without charged pions in the final state using a new T2K off-axis near detector WAGASCI-BabyMIND

K. Abe, S. Abe, R. Akutsu +398

We report a flux-integrated cross section measurement of muon neutrino interactions on water and hydrocarbon via charged current reactions without charged pions in the final state…

Testing T2K's Bayesian constraints with priors in alternate parameterisations

The T2K Collaboration, K. Abe, S. Abe +400

Bayesian analysis results require a choice of prior distribution. In long-baseline neutrino oscillation physics, the usual parameterisation of the mixing matrix induces a prior tha…
