Combining accelerator and reactor measurements of θ<inf>13</inf>: The first result

Abstract:

The lepton mixing angle θ13, the only unknown angle in the standard three-flavor neutrino mixing scheme, is finally measured by the recent reactor and accelerator neutrino experiments. We perform a combined analysis of the data coming from T2K, MINOS, Double Chooz, Daya Bay and RENO experiments and find sin22θ13 = 0.096 ± 0.013(±0.040) at 1 σ (3 σ) CL and that the hypothesis θ13 = 0 is now rejected at a significance level of 7.7 σ. We also discuss the near future expectation on the precision of the θ13 determination by using expected data from these ongoing experiments. © SISSA 2012.
