Recent studies of neutrino oscillations have established the existence of finite neutrino masses and mixing between generations of neutrinos [1]. The combined results from studies of atmospheric neutrinos, solar neutrinos, reactor antineutrinos and neutrinos produced at accelerators paint an intriguing picture that clearly requires modification of the standard model of particle physics. These r...

The phenomenon of neutrino oscillation has been firmly established: neutrinos change their flavour in their path from their source to observers. This paper is dedicated to the description of experimental results in the oscillation field, of their present understanding and of possible future developments in the experimental neutrino oscillation physics.

Although the first evidence for neutrino oscillations came from measurements on atmospheric neutrinos in underground experiments, neutrino oscillations have yet to be demonstrated in high energy neutrino telescopes, whose energy threshold is significantly higher. Recent studies have shown that a clean sample of atmospheric neutrinos with energies as low as 20 GeV can be isolated in the ANTARES ...

Large flux uncertainties and small cross sections have made neutrino scattering physics a challenge. However, a worthwhile challenge, as these tiny particle interactions can teach us a lot about neutrinos themselves, the weak interaction, and nucleon structure. As well, knowledge of these cross sections is crucial input to the growing field of neutrino oscillation physics. New, intense, well un...

In 1995 William Louis and colleagues at Los Alamos National Laboratory reported the first evidence of neutrino flavor oscillation in an accelerator experiment. The report was disquieting, and became more so over the next three years as its statistical significance was bolstered by more data from the LANL experiment. Why the disquiet? After all, neutrino oscillation, the metamorphosis of neutrin...

We point out a synergy between T-conjugated oscillation channels in the determination of the neutrino mass hierarchy with oscillation experiments with relatively short baselines (L . 700 km), where the matter effect is small. If information from all four oscillation channels νμ → νe, ν̄μ → ν̄e, νe → νμ and ν̄e → ν̄μ is available, a matter effect of few percent suffices to break the sign-degeneracy ...

We investigate the CP violation effect and the matter effect in the long-baseline neutrino oscillations in the four-neutrino model with mass scheme of the two pairs of two close masses separated by a gap of the order of 1 eV by using the constraints on the mixing matrix derived from the solar neutrino deficit, atmospheric neutrino anomaly, LSND experiments, and the other terrestrial neutrino os...
