Abstract

We present a study of the decays B-0,B-+ -> J/psi omega K-0,K-+ using 383 x 10(6) B (B) over bar events obtained with the BABAR detector at PEP-II. We observe Y(3940) -> J/psi omega, with mass 3914.6(-3.4)(+3.8)(stat) +/- 2.0(syst) MeV/c(2), and width 34(-8)(+12)(stat) +/- 5(syst) MeV. The ratio of B-0 and B+ decay to YK is 0.27(-0.23)(+0.28)(stat)(-0.01)(+0.04)(syst), and the relevant B-0 and B+ branching fractions are reported.
