Abstract

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 467±33 signal decays and measure SÏÏ=-0. 30±0.17(stat)±0.03(syst) and CÏÏ=-0. 09±0.15(stat)±0.04(syst). © 2005 The American Physical Society.
