We study the interplay of neutrino oscillation and invisible decay in atmospheric and long-baseline neutrinos experiments. We perform a global analysis of the full atmospheric data from Super-Kamiokande together with long-baseline K2K and MINOS in these scenarios. We find that the admixture of νμ → ντ oscillations with parameters ∆m232 = 2.6×10 −3 eV and θ23 ∼ 34 ◦ plus decay of the heavy neutrino, ν3, with lifetime of the order τ3/m3 ∼ 2.6× 10 −12 s/eV provides a reasonable fit to atmospheric… CONTINUE READING
