摘要：

We propose a new strategy for detecting the CP-violating phases and the effective mass of muon Majorana neutrinos by measuring observables associated with neutrino-antineutrino oscillations in pi(+/-) decays. Within the generic framework of quantum field theory, we compute the non-factorizable probability for producing a pair of same-charged muons in pi(+/-) decays as a distinctive signature of nu(mu) - (nu) over bar (mu) oscillations. Using the neutrino-antineutrino oscillation probability reported by MINOS collaboration, a new stringent bound on the effective muon-neutrino mass is derived.
