Exploring Leptonic CP Violation with Combined Analysis of Reactor and   Neutrino Superbeam Experiments
  We investigate the possibility to find the leptonic CP-violation by combining the reactor experiment with the superbeam experiment without antineutrino superbeam. We show also how much the sensitivity on CP-violating phase delta is affected by the fact that we have not known the sign of Delta m^2_31.
