Quantum dissipative effects and neutrinos: Current constraints and future perspectives

We establish the most stringent experimental constraints coming from recent terrestrial neutrino experiments on quantum mechanical decoherence eects in neutrino systems. Taking a completely phenomenological approach, we probe vacuum oscillations plus quantum decoherence between two neutrino species in the channels ! , ! e and e ! , admitting that the quantum decoherence parameter is related to the neutrino energy E as : = 0 E n ,w ithn = 1; 0; 1a nd 2. Our bounds are valid for a neutrino mass squared dierence compatible with the atmospheric, the solar and, in many cases, the LSND scale. We also qualitatively discuss the perspectives of the future long baseline neutrino experiments to further probe quantum dissipation.

Quest for the dynamics ofνμ→ντconversion

We perform a quantitative analysis of the capability of K2K, MINOS, OPERA and a neutrino factory in a muon collider to discriminate the standard mass induced vacuum oscillation from the pure decoherence solution to the atmospheric neutrino problem and thereby contribute to unravel the dynamics that governs the observed
