DFTT 55/99 hep-ph/9912211 Four-Neutrino Mixing and Long-Baseline Experiments
نویسنده
چکیده
We consider the two four-neutrino schemes that are compatible with all neutrino oscillation data. We present the range of the corresponding mixing parameters allowed by the results of neutrino oscillation experiments. We discuss the implications for long-baseline experiments and we suggest the possibility to reveal the presence of CP-violating phases through a comparison of the oscillation probability measured in long-baseline experiments with the corresponding average oscillation probability measured in short-baseline experiments.

DFTT 25/98 UWThPh-1998-24 hep-ph/9805411 Neutrino masses and mixing
We present a short review of the present status of the problem of neutrino masses and mixing. The existing experimental results indicate that there are at least four massive neutrinos. We show that only two schemes with mixing of four neutrinos and mass spectra in which two groups of close masses are separated by the \LSND gap" ( 1 eV) are compatible with the results of all neutrino oscillation...
متن کاملNeutrino masses and mixing from neutrino oscillation data
We discuss what information about the neutrino mass spectrum and the elements of the neutrino mixing matrix can be inferred from the results of neutrino oscillation experiments. The cases of three and four massive neutrinos are considered. It is shown that the general characteristics of the neutrino mixing matrix are quite different from those of the quark mixing matrix. Talk presented by S.M. ...
متن کاملDFTT 54/99 hep-ph/9910336 Four-Neutrino Oscillations
It is shown that at least four massive neutrinos are needed in order to accommodate the evidences in favor of neutrino oscillations found in solar and atmospheric neutrino experiments and in the LSND experiment. Among all four-neutrino schemes, only two, with a mass spectrum composed of two pairs of neutrinos with close masses separated by the “LSND gap” of the order of 1 eV, are compatible wit...

متن کاملFour-Neutrino Mixing and Big-Bang Nucleosynthesis
We investigate the Big-Bang Nucleosynthesis constraints on neutrino mixing in the framework of the two four-neutrino schemes that are favored by the results of neutrino oscillation experiments. We discuss the implications of these constraints for terrestrial short and long-baseline neutrino oscillation experiments and we present some possibilities of testing them in these experiments. In partic...
