Résumé

We present updated measurements of the CP-violating parameters SÏÏ and CÏÏ in B0â BO→+n- decays. Using a sample of 227 × 106 Î¥(4S)â→BB» decays collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC, we observe 467Â±33 signal decays and measure SÏÏ=-0. 30Â±0.17(stat)Â±0.03(syst) and CÏÏ=-0. 09Â±0.15(stat)Â±0.04(syst).
