Measuring theta sub 1 sub 3, and delta at future neutrino oscillation experiments: the problem of degeneracies

We discuss the physics reach of future neutrino oscillation experiments from a theoretical perspective, having as a guideline the problem of degeneracies. The presence of degenerate solutions in the measure of the neutrino oscillation parameters theta sub 1 sub 3, and delta is, in fact, the main problem that have to be addressed in planning future neutrino oscillation experiments. If degeneracies are not (at least partially) solved, it will be almost impossible to perform, at any future facility, precise measurements of theta sub 1 sub 3, and delta. After a pedagogical introduction on why degenerate solutions arise and how we can get rid of them, we analyze the physics reach of some of the planned neutrino experiment proposed: Super-Beams, Beta Beams and Neutrino Factories
