A study of time-dependent CP asymmetry in B0 --> J/psi pi0 decays
- SLAC
We present our first study of the time-dependent CP-violating asymmetry in B{sup 0} {yields} J/{psi}{pi}{sup 0} decays using e{sup +}e{sup -} annihilation data collected with the BABAR detector at the {Upsilon}(4S) resonance during the years 1999-2002 at the PEP-II asymmetric-energy B Factory at SLAC. With about 88 million B{bar B} pairs, our preliminary results for the coefficients of the cosine and sine terms of the CP asymmetry are C{sub J/{psi}{pi}{sup 0}} = 0.38 {+-} 0.41 (stat) {+-} 0.09 (syst) and S{sub J/{psi}{pi}{sup 0}} = 0.05 {+-} 0.49 (stat) {+-} 0.16 (syst).
