Probing CP violation with non-unitary mixing in long-baseline neutrino oscillation experiments: DUNE as a case study

F. J. Escrihuela, D. V. Forero, O. G. Miranda +2

When neutrino masses arise from the exchange of neutral heavy leptons, as in most seesaw schemes, the effective lepton mixing matrix $N$ describing neutrino propagation is non-unit…
