Abstract
We report a measurement of CP asymmetry parameters in the decay B{sup 0}(B{sup 0}){yields}J/{psi}{pi}{sup 0}, which is governed by the b{yields}ccd transition. The analysis is based on a 140 fb{sup -1} data sample accumulated at the {upsilon}(4S) resonance by the Belle detector at the KEKB asymmetric-energy e{sup +}e{sup -} collider. One neutral B meson in the J/{psi}{pi}{sup 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{sub J/{psi}}{sub {pi}}{sub {sup 0}}=-0.72{+-}0.42(stat){+-}0.09(syst) and A{sub J/{psi}}{sub {pi}}{sub {sup 0}}=-0.01{+-}0.29(stat){+-}0.03(syst)
