A Comparison of the Physics Potential of Future Long Baseline Neutrino Oscillation Experiments

We compare the generic physics potential of various combinations of conventional Wide Band or Neutrino Factory Beams with different detectors to determine several oscillation parameters in long baseline experiments. For each combination of beam and detector we show the precision which can be obtained for the leading oscillation parameters $\dm{31}$ and $\sin^2 2θ_{23}$. Furthermore we show the sensitivity to $\sin^2 2θ_{13}$ and the range in $\sin^2 2θ_{13}$ for which the sign of $\dm{31}$ can be extracted via matter effects. The results suggest that existing conventional Wide Band Beam and detector technology can be used to considerably improve the precision of neutrino properties until a neutrino factory will be built.

Masses and Mixings from Neutrino Beams pointing to Neutrino Telescopes

We discuss the potential to determine leading oscillation parameters, the value and the sign of Δm^2_{31}, as well as the magnitude of \sin^2 2θ_{13} using a conventional wide band neutrino beam pointing to water or ice Cherenkov neutrino detectors known as ``Neutrino Telescopes''. We find that precision measurements of Δm^2_{31} and θ_{23} are possible and that, even though it is not possible to discriminate between charges in the detector, there is a remarkably good sensitivity to the mixing angle θ_{13} and the sign of Δm^2_{31}.

CP-violation in neutrino oscillations

We study in a quantitative way CP-violating effects in neutrino oscillation experiments in the light of current and future data. Different scenarios with three and four neutrinos are worked out in detail including matter effects in long baseline experiments and it is shown that in some cases CP-violating effects could affect the analysis of a possible measurement. In particular in the three neutrino case we find that the effects can be larger than expected, at least in long-baseline $ν_μ\toν_e$. Moreover, measuring these effects could give useful information on the solar oscillation frequency. In four neutrino scenarios large effects are possible both in the $ν_μ\toν_τ$ and $ν_μ\toν_e$ channels of long-baseline experiments, whereas short-baseline experiments are affected only marginally.
