We review the present status of global analyses of neutrino oscillations, taking into account the most recent neutrino data including the latest KamLAND and K2K updates presented at Neutrino2004, as well as state-of-the-art solar and atmospheric neutrino flux calculations. We give the two-neutrino solar + KamLAND results, and the two-neutrino atmospheric + K2K oscillation regions, discussing in each case the robustness of the oscillation interpretation against departures from the Standard Solar Model and the possible existence of non-standard neutrino physics. Furthermore, we give the best fit values and allowed ranges of the three-flavour oscillation parameters from the current worlds' global neutrino data sample and discuss in detail the status of the small parameters α ≡ ∆m 2 sol /∆m 2 atm as well as sin 2 θ 13 , which characterize the strength of CP violating effects in neutrino oscillations. We also update the degree of rejection of four-neutrino interpretations of the LSND evidence in view of the most recent developments.PACS numbers: 26.65.+t, 13.15.+g, 14.60.Pq, 95.55.Vj
Here we update our previous global fit of neutrino oscillations by including
the recent results which have appeared since the Neutrino-2012 conference.
These include the measurements of reactor anti-neutrino disappearance reported
by Daya Bay and RENO, together with latest T2K and MINOS data including both
disappearance and appearance channels. We also include the revised results from
the third solar phase of Super-Kamiokande, SK-III, as well as new solar results
from the fourth phase of Super-Kamiokande, SK-IV. We find that the preferred
global determination of the atmospheric angle $\theta_{23}$ is consistent with
maximal mixing. We also determine the impact of the new data upon all the other
neutrino oscillation parameters with emphasis on the increasing sensitivity to
the CP phase, thanks to the interplay between accelerator and reactor data. In
the appendix we present the updated results obtained after the inclusion of new
reactor data presented at the Neutrino 2014 conference. We discuss their impact
on the global neutrino analysis.Comment: 13 pages, 5 figures, 2 tables. An appendix providing updated results
after Neutrino-2014 Conference is added. Matches published version in
