Decoherence, matter effect, and neutrino hierarchy signature in long baseline experiments

Abstract : Environmental decoherence of oscillating neutrinos of strength Γ=(2.3±1.1)×10-23  GeV can explain how maximal θ23 mixing observed at 295 km by T2K appears to be nonmaximal at longer baselines. As shown recently by R. Oliveira, the Mikheyev-Smirnov-Wolfenstein matter effect for neutrinos is altered by decoherence: in normal (inverted) mass hierarchy, a resonant enhancement of νμ(ν¯μ)→νe(ν¯e) occurs for 6
