Where we are on θ13: addendum to 'Global neutrino data and recent reactor fluxes: status of three-flavor oscillation parameters' (vol 13, 109401, 2011)

TLDR
In this paper, the authors consider the recent results from long-baseline νμ−→−νe searches at the Tokai to Kamioka (T2K) and Main Injector Neutrino Oscillation Search (MINOS) experiments and investigate their implications for the mixing angle θ13 and the leptonic Dirac CP phase δ.
Abstract
In this addendum to Schwetz et al (2011 New J. Phys.13 063004), we consider the recent results from long-baseline νμ → νe searches at the Tokai to Kamioka (T2K) and Main Injector Neutrino Oscillation Search (MINOS) experiments and investigate their implications for the mixing angle θ13 and the leptonic Dirac CP phase δ. By combining the 2.5σ indication for a nonzero value of θ13 coming from the T2K data with global neutrino oscillation data, we obtain a significance for θ13 > 0 of about 3σ with best fit points sin2 θ13 = 0.013 (0.016) for normal (inverted) neutrino mass ordering. These results depend somewhat on assumptions concerning the analysis of reactor neutrino data.

Matter and antimatter in the universe

TL;DR: In this article, the authors review observational evidence for a matter-antimatter asymme-try in the early universe, which leads to the remnant matter density we observe today and discuss bounds on the presence of antimatter in the present-day universe, including the possibility of a large lepton asymmetry in the cosmic neutrino background.

Finite modular groups and lepton mixing

TL;DR: In this paper, the authors studied lepton mixing patterns derived from finite modular groups Γ N, requiring subgroups G ν and G e to be preserved in the neutrino and charged lepton sectors, respectively.

Indication of Electron Neutrino Appearance from an Accelerator-produced Off-axis Muon Neutrino Beam

K. Abe, +416 more
TL;DR: The T2K experiment observes indications of ν (μ) → ν(e) appearance in data accumulated with 1.43×10(20) protons on target, and under this hypothesis, the probability to observe six or more candidate events is 7×10(-3), equivalent to 2.5σ significance.

Improved Predictions of Reactor Antineutrino Spectra

TL;DR: In this paper, the authors report new calculations of antineutrino spectra including the latest information from nuclear databases and a detailed error budget, which is based on the so-called ab initio approach where the sum of all beta-branches of all fission products predicted by an evolution code.
