        abstract = {We report a measurement of CP asymmetry parameters in the decay B-0((B) over bar (0))--{\ensuremath{>}}J/psipi(0), which is governed by the b--{\ensuremath{>}}c(c) over bar d transition. The analysis is based on a 140 fb(-1) data sample accumulated at the Y(4S) resonance by the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. One neutral B meson in the J/psipi(0) final state is fully reconstructed for events used in this analysis. The accompanying B meson flavor is identified by its decay products. From the distribution of proper-time intervals between the two B decays, we obtain the following CP-violating parameters: S-J/psipi(0)=-0.72+/-0.42(stat)+/-0.09(syst) and A(J/psipi)(0)=-0.01+/-0.29(stat)+/-0.03(syst).}
