Prospects of accelerator and reactor neutrino oscillation experiments for the coming ten years

We analyze the physics potential of long-baseline neutrino oscillation experiments planned for the coming ten years, where the main focus is the sensitivity limit to the small mixing angle ${\theta }_{13}$. The discussed experiments include the conventional beam experiments MINOS, ICARUS, and OPERA, which are under construction, the planned superbeam experiments J-PARC to Super-Kamiokande and NuMI off-axis, as well as new reactor experiments with near and far detectors, represented by the Double-Chooz project. We perform a complete numerical simulation including systematics, correlations, and degeneracies on an equal footing for all experiments using the GLoBES software. After discussing the improvement of our knowledge on the atmospheric parameters ${\theta }_{23}$ and $\Delta m_{31}^2$ by these experiments, we investigate the potential to determine ${\theta }_{13}$ within the next ten years in detail. Furthermore, we show that under optimistic assumptions and for ${\theta }_{13}$ close to the current bound, even the next generation of experiments might provide some information on the Dirac CP phase and the type of the neutrino mass hierarchy.
