Toward diagnosing neutrino non-unitarity through CP phase correlations
Toward diagnosing neutrino non-unitarity through CP phase correlations
Abstract We discuss correlations between the neutrino-mass-embedded Standard Model CP phase δ and the phases that originate from new physics which cause neutrino-sector unitarity violation (UV) at low energies. This study aims to provide one of the building blocks for machinery to diagnose non-unitarity, our ultimate goal. We extend the …
