Long baseline neutrino oscillations and leptonic CP violation

Abstract

The status of 3-generation lepton mixing is reviewed. Future possible neutrino facilities using: i ) intense conventional ν ( − ) μ sources, ii ) superbeams and iii ) neutrino factories are discussed. Properties of CP-violating asymmetries are described. It is shown that our ability to measure the CP-violating phase δ is rather insensitive to the specific value of θ 13 for 0.01 ⩽ sin 2 2 θ 13 ≲ 0.20 , as well as the detector distance (for very long distances). The potential for making precision measurements of all neutrino oscillation parameters ( θ i j , Δ m i j 2 , δ ) using a wide band ν μ beam is explained using results of a Brookhaven-Homestake (2540km) study. An outlook on the future is given.
