Ratios of bottom meson branching fractions involving J/ψ mesons and determination of b quark fragmentation fractions
Abstract
We report a measurement of the ratios of the decay rates of the B+, B0, and B0s mesons into exclusive final states containing a J/ψ meson. The final states were selected from 19.6 pb-1 of pp¯ collisions recorded by the Collider Detector at Fermilab. These data are interpreted to determine the b quark fragmentation fractions fu, fd, and fs. We also determine the branching fractions for the decay modes B+-->J/ψK+, B+-->J/ψK*(892)+, B0-->J/ψK0, B0-->J/ψK*(892)0, and B0s-->J/ψφ(1020). We discuss the implications of these measurements to B meson decay models.
