| Abstract;We consider the search for the leptonic CP-violation angle by long baseline neutrino oscillation experiments using a .NU..MU. superbeam. The ambiguity of .DELTA.m31'2' obscures the .NU.e appearance probability and also make the .DELTA.CP search more difficult. It is shown that we can precusely determine the value of .DELTA.m31'2' using the large number of .NU..MU. survival events expected from the large .NU..MU.-flux in .NU..MU. superbeams. We also show that the combined analysis of .NU.e appearance and .NU..MU. survival events can place strong constraints on the values of .DELTA.CP and .DELTA.m31'2'. |
