Measurement of Inclusive B --> psi Production
Anderson, S.
Original · EN
Using the combined CLEO II and CLEO II.V data sets of 9.1 fb⁻¹ at the Upsilon(4S), we measure properties of Psi mesons produced directly from decays of the B meson, where ``B'' denotes an admixture of B+, B-, B0, and B0bar, and ``Psi'' denotes either J/Psi or Psi(2S). We report first measurements of Psi polarization in B -> Psi(direct) X: alpha(J/Psi) = -0.30 +0.07 -0.06 stat +-0.04 syst and alpha(Psi(2S)) = -0.45 +0.22 -0.19 stat +-0.04 syst. We also report improved measurements of the momentum distributions of Psi produced directly from B decays, correcting for measurement smearing. Finally, we report measurements of the inclusive branching fraction for B -> Psi X and B -> Chic1 X.
