“…It has been known for quite a long time that the most prominent oscillation channel for the study of threeflavor and matter effects in long-baseline experiments like neutrino factories is the so-called golden channel ν e → ν µ (Barger et al, 1980c;Cervera et al, 2000;De Rujula et al, 1999;Dick et al, 1999;Donini et al, 2000;Freund et al, 2000;Minakata and Nunokawa, 1997;Tanimoto, 1997). The exact formulas for the oscillation probabilities in matter are quite cumbersome due to the large number of parameters involved (Ohlsson and Snellman, 2000;Zaglauer and Schwarzer, 1988).…”

Several topics on CP violation in the lepton sector are reviewed. A few theoretical aspects concerning neutrino masses, leptonic mixing, and CP violation will be covered, with special emphasis on seesaw models. A discussion is provided on observable effects which are manifest in the presence of CP violation, particularly, in neutrino oscillations and neutrinoless double beta decay processes, and their possible implications in collider experiments such as the LHC. The role that leptonic CP violation may have played in the generation of the baryon asymmetry of the Universe through the mechanism of leptogenesis is also discussed.

“…∆m 2 21 = 0. We have thus two leading oscillation parameters (θ 23 and ∆m 2 ) and two sub-leading parameters (θ 13 and sgn ∆m 2 ) and no effects from the CP-violating phase δ [2]. This approximation is justified since CP-violating effects disappear quickly for the large distances considered [5].…”

(especially θ 13 ) would be very important [2]. We perform therefore in this paper a global comparison of the generic physics potential of several experimental setups and we present the resulting precision of the leading oscillation parameters (∆m 2 31 and θ 23 ) as well as the sensitivity to the sub-leading parameters (θ 13 and the sign of ∆m 2 31 ).…”

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 ∆m 2 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 ∆m 2 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.Recent studies of neutrino factories as powerful neutrino sources have shown that precision measurements of neutrino masses and mixings are possible in the future [1]. The development of a neutrino factory includes however challenging technological issues and the development will certainly take some time. It is therefore of interest what can be achieved meanwhile in comparison by using conventional neutrino beams. Such improved conventional experiments will lead to a better knowledge of neutrino parameters, which might be considered as a useful step to simply bridge the time until a neutrino factory will be operating. We will however show in this paper that conventional setups may be able to compete in some aspects with the long baseline neutrino oscillation program of neutrino factories. The results of such intermediate experiments would also be important since they affect the optimal strategies for neutrino factories. This applies especially to the measurement of CPviolation at neutrino factories, where further advance information on the mixing parameters *
