abstract

The presence of non-unitary neutrino mixing can affect the measurement of the three-neutrino leptonic Dirac CP phase and hamper efforts to probe CP violation due to degeneracies of the extra non-unitary CP phase with the standard CP phase. We study the effect of including non-unitarity on probing CP violation with the long-baseline experiments NO$\nu$A, T2K and DUNE. We analyze the effect of non-unitary mixing at the level of oscillation probabilities associated with the relevant baselines, and present the CP violation sensitivity for the individual experiments and their combination. Our results show that there is an improvement in the CP violation sensitivity of the combination compared to the individual experiments.

  1. Physics of parameter correlations around the solar-scale enhancement in neutrino theory with unitarity violation

    hep-ph 2019-08 conditional novelty 5.0 of 10

    A new first-order perturbation theory for solar-scale neutrino oscillations with non-unitary mixing shows that δ and the non-unitarity α parameters form physical, convention-independent phase correlations.
