“…Additionally, its possible group theoretic origin from a more fundamental symmetry such as A 4 have been investigated [37][38][39][40]. However, this flavor symmetry leads to the prediction that θ 13 = 0 which has now been excluded at more than 5.2σ [41]. A way out was proposed [32][33][34] in terms of its complex (CP) extension (CP µτ ) with the postulate…”

We propose a complex extension of µτ permutation antisymmetry in the neutrino Majorana matrix M ν . The latter can be realized for the Lagrangian by appropriate CP transformations on the neutrino fields. The resultant form of M ν is shown to be simply related to that with a complex (CP) extension of µτ permutation symmetry, with identical phenomenological consequences, though their group theoretic origins are quite different. We investigate those consequences in detail for the minimal seesaw induced by two strongly hierarchical right-chiral neutrinos N 1 and N 2 with the result that the Dirac phase is maximal while the two Majorana phases are either 0 or π. We further provide an uptodate discussion of the ββ0ν process vis-a-vis ongoing and forthcoming experiments. Finally, a thorough treatment is given of baryogenesis via leptogenesis in this scenario, primarily with the assumption that the lepton asymmetry produced by the decays of N 1 only matters here with the asymmetry produced by N 2 being washed out. Tight upper and lower bounds on the mass of N 1 are obtained from the constraint of obtaining the correct observed range of the baryon asymmetry parameter and the role played by N 2 is elucidated thereafter. The mildly hierarchical right-chiral neutrino case (including the quasidegenerate possibility) is discussed in an appendix.

“…The 3 + 1 scheme naturally predicts sizable effects at the short baselines, where the oscillating factor ∆ 41 ≡ ∆m 2 41 L/4E (L being the baseline and E the neutrino energy) is of order one, and one expects an oscillating behavior with the characteristic L/E dependency. However, it must be emphasized that sterile neutrinos are observable in other (non-shortbaseline) types of experiments where they may manifest in a more subtle way.…”

“…In fact, a few anomalies have been recorded at the short baseline experiments, which cannot be accommodated in the 3-flavor scheme (see [6][7][8] for a review of the topic). The two standard mass-squared splittings ∆m 2 21 ≡ m 2 2 − m 2 1 and ∆m 2 31 ≡ m 2 3 − m 2 1 are too small to produce observable effects in such setups and (at least) one new much larger masssquared difference O(eV 2 ) must be introduced. The hypothetical fourth mass eigenstate must be essentially sterile.…”

“…The enlarged scheme must be realized in such a way to preserve the very good description of all the other (non short-baseline) data. In the minimal extension, involving only one sterile species, the so-called 3 + 1 scheme, the new mass eigenstate ν 4 is assumed to be weakly mixed with the active neutrino flavors (ν e , ν µ , ν τ ) and it is separated from the standard mass eigenstates (ν 1 , ν 2 , ν 3 ) by a large O(eV 2 ) splitting, giving rise to the hierarchical pattern |∆m 2 21 | |∆m 2 31 | |∆m 2 41 |. The 3+1 scheme involves six mixing angles and three (Dirac) CP-violating phases.…”

“…Such a 3-flavor framework involves two distinct masssquared splittings (∆m 2 31 , ∆m 2 21 ), three mixing angles (θ 12 , θ 23 , θ 13 ), and one CP-phase δ. The latest fundamental step in the establishment of the 3-flavor scheme has been accomplished very recently (during 2012), with the determination of the long-sought third mixing angle θ 13 by means of dedicated reactor experiments [2][3][4]. This discovery has -1 -…”

Abstract:We study the impact of one light sterile neutrino on the prospective data expected to come from the two presently running long-baseline experiments T2K and NOνA when they will accumulate their full planned exposure. Introducing for the first time, the bi-probability representation in the 4-flavor framework, commonly used in the 3-flavor scenario, we present a detailed discussion of the behavior of the ν µ → ν e andν µ →ν e transition probabilities in the 3+1 scheme. We also perform a detailed sensitivity study of these two experiments (both in the stand-alone and combined modes) to assess their discovery reach in the presence of a light sterile neutrino. For realistic benchmark values of the mass-mixing parameters (as inferred from the existing global short-baseline fits), we find that the performance of both these experiments in claiming the discovery of the CP-violation induced by the standard CP-phase δ 13 ≡ δ, and the neutrino mass hierarchy get substantially deteriorated. The exact loss of sensitivity depends on the value of the unknown CP-phase δ 14 . Finally, we estimate the discovery potential of total CP-violation (i.e., induced simultaneously by the two CP-phases δ 13 and δ 14 ), and the capability of the two experiments of reconstructing the true values of such CP-phases. The typical (1σ level) uncertainties on the reconstructed phases are approximately 40 0 for δ 13 and 50 0 for δ 14 .
