Evidence for CP violation in B-0 -> J/psi pi(0) decays

Evidence for CP violation in B-0 -> J/psi pi(0) decays

We present measurements of the branching fraction and time-dependent CP asymmetries in B0→J/ψπ0 decays based on 466×106 Υ(4S)→BB̄ events collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. We measure the CP asymmetry parameters S=-1.23±0.21(stat)±0.04(syst) and C=-0.20±...
