Description
We investigate precisely what can be extracted from the current appearance and disappearance oscillation data in regards the 3x3 PMNS matrix, without explicitly assuming unitarity. Our cannonical model of this unitarity violation is an added sterile neutrino, whose mass and mixing are not fully resolvable in current generation experiments, or does not take part in oscillations. Further constraints on deviations from unitarity from lepton universality and rare lepton decays are discussed to further bound the lepton mixing matrix, and future experiments that can improve the situation are investigated.
