Title: “News on θ13 from MINOS and T2K”


Abstract:


Compelling evidence exists for the flavour oscillations of neutrinos,
but there remains one mixing angle, theta_13, which has yet to be
definitively measured. The T2K and MINOS collaborations recently
reported on their nu_e appearance analysis. T2K presented results from
the first 2 runs periods using data from 1.43E20 protons on target, and
the results provide an indication that this angle is non-zero.
MINOS updated their analysis using 8e20 protons on target. A short
overview of the experiments and fuller discussion of the results will be presented.
Combining the data from the experiments may lead to a 3 sigma discovery of θ13.
