摘要
In a study of a muon-neutrino disappearance at 810 km, the NOvA experiment finds flavor mixing of the atmospheric sector to deviate from maximal (sin(2) theta(23) = 0.5) by 2.6 sigma. The result is in tension with the 295-km baseline measurements of T2K, which are consistent with maximal mixing. We propose that theta(23) is in fact maximal, and that the disagreement is a harbinger of environmentally induced decoherence. The departure from maximal mixing can be accounted for by an energy-independent decoherence of strength Gamma = (2.3 +/- 1.1) x 10(-23) GeV.
