Query: Evidence of theta(13)>0 from global neutrino data analysis   The neutrino mixing angle theta(13) is at the focus of current neutrino
research. From a global analysis of the available oscillation data in a
3-neutrino framework, we previously reported [Phys. Rev. Lett. 101, 141801
(2008)] hints in favor of theta(13)>0 at the 90 % C.L. Such hints are
consistent with the recent indications of nu(mu)-->nu(e) appearance in the T2K
and MINOS long-baseline accelerator experiments. Our global analysis of all the
available data currently provides >3 sigma evidence for nonzero theta(13), with
1-sigma ranges sin^2 theta(13) = 0.021+-0.007 or 0.025+-0.007, depending on
reactor neutrino flux systematics. Updated ranges are also reported for the
other 3-neutrino oscillation parameters (delta m^2, sin^2 theta(12)) and (Delta
m^2, sin^2 theta(23)).
