Abstract

We report a measurement of the ratios of the decay rates of the B⁺, B⁰, and B⁰ _s 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 f_u, f_d, and f_s. We also determine the branching fractions for the decay modes (formula presented). We discuss the implications of these measurements to B meson decay models.
