Quest for the dynamics of conversion
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 disappearence.Comment: 34 pages, 12 figure
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 effects in
neutrino systems. Taking a completely phenomenological approach, we probe
vacuum oscillations plus quantum decoherence between two neutrino species in
the channels , and , admitting that the quantum decoherence parameter is related
to the neutrino energy as : ,
with and 2. Our bounds are valid for a neutrino mass squared
difference 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.Comment: 26 pages, 8 encapsulated postscript figure
