CERN to Gran Sasso; An ideal distance for superbeam?

Abstract

We use the CP trajectory diagram as a tool for pictorial representation of the genuine CP and the matter effects to explore the possibility of an in situ simultaneous measurement of δand the sign of Δm^2_{13}. We end up with a low-energy conventional superbeam experiment with a megaton-class water Cherenkov detector and baseline length of about 700 km. A picturesque description of the combined ambiguity which may arise in simultaneous determination of θ_{13} and the above two quantities is given in terms of CP trajectory diagram.
