Abstract

The CP asymmetry parameters in the decay B ⁰(B̄ ⁰) → J/ψπ ⁰, were described. The measurement of the CP asymmetry parameters was based on a 140 fb ^-1 data sample, which was accumulated at the γ(4S) resonance by the Belle detector at the KEKB asymmetric-energy e ⁺e ^- collider. It was observed that one neutral B meson flavor was identified by its decay products. The results show values of the CP-violating parameters were found to be of the order of S _J/ψπ ^o = -0.72∓0.42(stat)∓0.09(syst) and A _J/ψπ ⁰ = -0.01∓0.29(stat)∓0. 03(syst).
