“…The latest results from the NOνA long baseline experiment favour a ∼ 5 • deviation of the atmospheric mixing angle from maximal mixing [20], while the results from the T2K long baseline experiment [21] and from the IceCube neutrino detector [22] do not find evidence of such deviation so far, so that a mild tension exists but still within 90% C.L. At the same time both experiments strengthen the support for negative values of sin δ.…”

Recent encouraging experimental results on neutrino mixing parameters prompt further investigation on SO(10)-inspired leptogenesis and on the associated strong thermal solution that has correctly predicted a non-vanishing reactor mixing angle, it further predicts sin δ 0, now supported by recent results at ∼ 95% C.L., normally ordered neutrino masses and atmospheric mixing angle in the first octant, best fit results in latest global analyses. Extending a recent analytical procedure, we account for the mismatch between the Yukawa basis and the weak basis, that in SO(10)-inspired models is described by a CKM-like unitary transformation V L , obtaining a full analytical solution that provides useful insight and reproduces accurately all numerical results, paving the way for future inclusion of different sources of theoretical uncertainties and for a statistical analysis of the constraints. We show how muon-dominated solutions appear for large values of the lightest neutrino mass in the range (0.01-1) eV but also how they necessarily require a mild fine tuning in the seesaw relation. For the dominant (and untuned) tauon-dominated solutions we show analytically how, turning on V L V CKM , some of the constraints on the low energy neutrino parameters get significantly relaxed. In particular we show how the upper bound on the atmospheric neutrino mixing angle in the strong thermal solution gets relaxed from θ 23 41 • to θ 23 44 • , an important effect in the light of the most recent NOνA, T2K and IceCube results.

The NOvA experiment at Fermilab uses a beam of neutrinos and two detectors separated by an 810 km baseline to observe muon neutrino disappearance and electron neutrino appearance. These measurements have the potential to reveal the remaining unknowns in neutrino oscillations, namely the mass hierarchy, the θ 23 octant, and perhaps even hint at the violation of CP in the neutrino sector. In this talk, I will describe the current status of the NOvA experiment, present results and discuss future sensitivities.

“…The absolute neutrino mass scale is not known either, but subject to the constraint m 1 + m 2 + m 3 < 0.23 eV from cosmological observations [3]. Particularly noteworthy, a recent result from the NOvA experiment (θ 23 = 39.5 • ± 1.7 • or 52.1 • ± 1.7 • in the NH case) disfavors the popular maximal mixing scenario θ 23 = 45 • with 2.6σ significance [4]. On the other hand, it is…”

Breakings of the neutrino μ-τ reflection symmetry

The neutrino µ-τ reflection symmetry has been attracting a lot of attention as it predicts the interesting results θ 23 = π/4 and δ = ±π/2. But it is reasonable to consider breakings of such a symmetry either from the theoretical considerations or on the basis of experimental results. We thus perform a systematic study for the possible symmetrybreaking patterns and their implications for the mixing parameters. The general treatment is applied to some specific symmetry breaking arising from the renormalization group effects for illustration.
