Abstract
A new technique to measure the ratio of b quark fragmentation fractions in (Formula presented) collisions is described. Using a (Formula presented) sample of low-mass dimuon trigger data recorded with the Collider Detector at Fermilab, we identify B mesons by observing the double semileptonic decays (Formula presented) with (Formula presented) By counting the numbers of (Formula presented) (Formula presented) and φ(1020) mesons produced in association with these muon pairs, we measure the ratio of strange to nonstrange B meson production to be (Formula presented) This measurement is the most precise available from hadron collisions to date. Limits on the branching fractions of semileptonic charm meson decays with (Formula presented) (Formula presented) and (Formula presented) mesons in the final state are also obtained. © 1999 The American Physical Society.
