SNO, KamLAND and neutrino oscillations: THETA(13)

At the previous Venice meeting NO-VE 2008, we discussed possible hints in favour of a nonzero value for the unknown neutrino mixing angle θ13, emerging from the combination of solar and long baseline reactor data (SNO+KamLAND), as well as from the combination of atmospheric (Super-Kamiokande) data with CHOOZ and lon-baseline accelerator νμ->→νμ data. Recent MINOS 2009 results in the νμ→νe appearance channel also seem to support such hints. A combination of all current oscillation data provides, as preferred range, sin2θ13 ∼0.02±0.01 (1σ). We reviewed several issued raised by such hints in the last year, and comment on their possible near-future improvements and tests.
