“…These 1-loop contributions provide the solar mass square splitting. Due to the flavor symmetry and vacuum alignment, one neutrino is nearly massles and there is a non-trivial restriction upon the neutrino oscillation parameters, displayed in figures 1-3, consistent however with the most recent experimental data presented at the recent Neutrino 2012 conference and the corresponding neutrino oscillation global fits [43][44][45][46][47]. As far as collider physics is concerned, our model predicts that LSP decays and neutrino mixing angles are tightly correlated, opening encourageing expectations for searches at the LHC [35].…”

Bilinear R-parity violation (BRPV) provides the simplest intrinsically supersymmetric neutrino mass generation scheme. While neutrino mixing parameters can be probed in high energy accelerators, they are unfortunately not predicted by the theory. Here we propose a model based on the discrete flavor symmetry A 4 with a single R-parity violating parameter, leading to (i) correct Cabbibo mixing given by the Gatto-Sartori-Tonin formula, and a successful unification-like b-tau mass relation, and (ii) a correlation between the lepton mixing angles θ 13 and θ 23 in agreement with recent neutrino oscillation data, as well as a (nearly) massless neutrino, leading to absence of neutrinoless double beta decay.

“…7 See also previous analyses in [46,47]. 8 The main difference is the presence of two allowed octants for the atmospheric mixing in the analyses of [43,[45][46][47] while only one octant is present in the Bari group analysis, since it is more strongly preferred in that case [44]. Figure 1.…”

“…The issue of possible nonzero θ 13 has been discussed in the context of global analyses which include the solar and the atmospheric neutrino data even before [23][24][25] or after [26,27] the T2K result [9]. However, given the current precision on the determination of θ 13 , such global fits seem unnecessary in this specific context.…”

Abstract:The lepton mixing angle θ 13 , the only unknown angle in the standard threeflavor neutrino mixing scheme, is finally measured by the recent reactor and accelerator neutrino experiments. We perform a combined analysis of the data coming from T2K, MINOS, Double Chooz, Daya Bay and RENO experiments and find sin 2 2θ 13 = 0.096 ± 0.013(±0.040) at 1 σ (3 σ) CL and that the hypothesis θ 13 = 0 is now rejected at a significance level of 7.7 σ. We also discuss the near future expectation on the precision of the θ 13 determination by using expected data from these ongoing experiments.

“…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],…”
