Abstract

We report a measurement of the CP-violation parameter sin 2beta with B-0-->J/psiK(S)(0) decays in which the J/psi decays to hadrons or to muons that do not satisfy our standard identification criteria. With a sample of 88 million B (B) over bar events collected by the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC, we reconstruct 100+/-17 such events, with J/psi-->pi(+)pi(-)pi(0) being the most prevalent, and measure sin 2beta=1.56+/-0.42(stat)+/-0.21(syst).
