摘要：

We propose the indirect search for the CP violating phase in the long baseline nu(mu) --> nu(e) oscillation experiment, in which two scenarios of the neutrino mass hierarchy are discussed in the three family model. The CP violating phase effect is clearly found in the scenario: the LSND data plus the atmospheric neutrino deficit. The phase dependence of the oscillation probability is explicitly shown by using typical parameters of the K2K experiment. The matter effect is negligibly small. In order to select the scenario of the neutrino mass hierarchy, the measurement of the nu(e) --> nu(tau) oscillation is also proposed in the long baseline experiment. (C) 1998 Elsevier Science B.V.
