Available in PDF, EPUB and Kindle. Book excerpt: We present our first study of the time-dependent CP-violating asymmetry in B° 2!J/[psi][pi]° decays using ee− 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]°} = 0.38 ± 0.41 (stat) ± 0.09 (syst) and S{sub J/{psi}[pi]°} = 0.05 ± 0.49 (stat) ± 0.16 (syst).
