Title: Cp Trajectory Diagram - A Tool For A Pictorial Representation Of Cp And Matter Effects In Neutrino Oscillations
Author: Minakata H.

Abstract: We introduce a "CP trajectory diagram in bi-probability space" as a powerful tool for a pictorial representation of the genuine CP and the matter effects in neutrino oscillations. The existence of correlated ambiguity in the determination of CP-violating phase δ and the sign of Δm132 is uncovered. The principles of tuning the beam energy for a given baseline distance are proposed to resolve the ambiguity and to maximize the CP-odd effect. We finally point out, quite contrary to what is usually believed, that the ambiguity may be resolved with ∼50% chance in the super-JHF experiment despite its relatively short baseline of 300 km. © 2003 Elsevier Science B.V.
