Description:

Abstract: The long-baseline neutrino experiments continue to provide precision measurements of neutrino oscillation parameters by searching for the appearance of electron (anti)neutrinos and the disappearance of muon (anti)neutrinos in a beam of muon (anti)neutrinos. However, fundamental questions such as the neutrino mass ordering and the charge-parity violation in neutrinos remain unknown. The NOvA and T2K experiments continue to take data while the Deep Underground Neutrino Experiment (DUNE) is the next generation long-baseline neutrino oscillation experiment. DUNE will feature the most intense accelerator neutrino beam in the world and achieve extraordinary precision by employing and advancing the liquid argon (LAr) detector technology.

In this talk, I will present the latest results from the NOvA and the T2K experiments, providing a snapshot of the latest accelerator-based neutrino oscillation measurements. I will discuss the current status of the combined joint-fit analysis of the NOvA and T2K data which will not only provide a significantly tighter statistical constraint but will also be useful for breaking degeneracies in the individual measurements. For DUNE to achieve its stated sensitivities, it will include a suite of near detectors to constrain systematic uncertainties within a few percent levels.  I will discuss the ongoing prototype efforts to test the novel techniques that will be used in the modular ND-LAr for DUNE and showcase the preliminary results from cosmic ray runs.
