We report the results of a search for ν(e) appearance in a ν(μ) beam in the MINOS long-baseline neutrino experiment. With an improved analysis and an increased exposure of 8.2 × 10(20) protons on the NuMI target at Fermilab, we find that 2 sin(2) (θ(23))sin(2)(2θ(13))<0.12(0.20) at 90% confidence level for δ = 0 and the normal (inverted) neutrino mass hierarchy, with a best-fit of 2sin(2) (θ(23))sin(2)(2θ(13)) = 0.041(-0.031)(+0.047) (0.079(-0.053) (+0.071)). The θ(13) = 0 hypothesis is disfavored by the MINOS data at the 89% confidence level.

- Current unknowns in the three-neutrino framework (2018, background): “Since the review in [1] (when only θ12 and θ23 were measured), dramatic progress has occurred concerning θ13 [15], starting from hints from solar, reactor and atmospheric data [16], to growing evidence from accelerator data [17, 18, 19, 20] and finally to its discovery and precise determination via ”
