description

We discuss the results of an updated global analysis of neutrino oscillation data, focusing on the determination of θ13, the smallest and unknown leptonic mixing angle. We discuss three independent and converging hints of θ13 > 0: a first one coming from atmospheric neutrino data; a second one from the combination of solar and long-baseline reactor (KamLAND) neutrino data; and a third one from the latest MINOS measurements in the appearance (νμ → νe) channel. Their combination provides an indication for θ13 > 0 at the 2σ (95% C.L.) level.
