Neutrino Mixing Anarchy: Alive and Kicking
arXiv:1204.1249
Abstract
Neutrino mixing anarchy is the hypothesis that the leptonic mixing matrix can be described as the result of a random draw from an unbiased distribution of unitary three-by-three matrices. In light of the recent very strong evidence for a nonzero sin^2(theta_13), we show that the anarchy hypothesis is consistent with the choice made by the Nature -- the probability of a more unusual choice is 44%. We revisit anarchy's ability to make predictions, concentrating on correlations - or lack thereof - among the different neutrino mixing parameters, especially sin^2(theta_13) and sin^2(theta_23). We also comment on anarchical expectations regarding the magnitude of CP-violation in the lepton sector, and potential connections to underlying flavor models or the landscape.
