“…Existing global fits to a suite of neutrino oscillation experiments are summarized in the Table I for both normal hierarchy (NH) and inverted hierarchy (IH) scenarios [7] (see also, [8][9][10] and [11][12][13]). The experimental observation of a large lepton mixing angle θ 13 8 • − 10 • is clearly incompatible with the so-called Tri-Bimaximal Mixing (TBM) pattern [14],…”

Broken S3 symmetry in the neutrino mass matrix and non-zero θ13

We study the effects of breaking S 3 symmetry in the neutrino mass matrix for the masses and mixing matrix of neutrinos. At zeroth order the model gives degenerate neutrino masses and accommodates tribimaximal mixing. We introduce perturbations in terms of a small and complex parameter. The perturbations are introduced in a manner such that the S 3 symmetry is broken by its elements in the same representation. Successive perturbations introduce mass splitting, sizable non-zero reactor mixing angle and CP violation. This scheme of breaking S 3 symmetry can reproduce a relatively large reactor mixing angle as suggested by the recent T2K results. The effective neutrino mass is predicted to be large which is testable in the ongoing and forthcoming neutrinoless double beta decay experiments. IntroductionAfter the discovery of neutrino oscillations, there has been considerable progress in determining the values of the neutrino mass-squared differences and the mixing angles which relate the neutrino mass eigenstates to the flavor eigenstates. Recently, T2K [1], MINOS [2] and Double Chooz [3] experiments have given hints of a relatively large 1-3 mixing angle. This has given a fresh impetus to the construction of neutrino mass models which can accommodate a non-zero value of θ 13 . Recently many papers have appeared which reproduce the * dev5703@yahoo.com †

“…Indications of a nonzero θ 13 value were reported by two accelerator appearance experiments, T2K [6] and MINOS [7], and by the Double Chooz reactor disappearance experiment in 2011 [8]. Global analyses of all available neutrino oscillation data have indicated central values of sin 2 (2θ 13 ) that are between 0.05 and 0.1 (see e.g., [9,10]). In 2012, Daya Bay and RENO reported definitive measurements of the mixing angle θ 13 based on the disappearance of reactor electron antineutrinos [11,12].…”

Abstract. Definitive measurements of the smallest neutrino mixing angle θ 13 were made by Daya Bay, Double Chooz and RENO in 2012, based on the disappearance of electron antineutrinos emitted from reactors. The new generation reactor experiments have significantly improved a sensitivity for θ 13 down to the sin 2 (2θ 13 )~0.01 level using two identical detectors of 10 ~ 40 tons at near (300 ~ 400 m) and far (1 ~ 2 km) locations. The θ 13 measurements by the three reactor experiments are presented with their future expected sensitivities.
