Abstract
We present updated measurements of the CP-violating parameters Sππ and Cππ in B0→π+π- decays. Using a sample of 227×106 Υ(4S)→BB̅ 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 Sππ=-0.30±0.17(stat)±0.03(syst) and Cππ=-0.09±0.15(stat)±0.04(syst).
