Abstract:

A new technique to measure the ratio of b quark fragmentation fractions in pp̄ collisions is described. Using a 70-pb-1 sample of low-mass dimuon trigger data recorded with the Collider Detector at Fermilab, we identify B mesons by observing the double semileptonic decays b→c μX with c→s μX. By counting the numbers of K*(892)0, K*(892)+, and φ(1020) mesons produced in association with these muon pairs, we measure the ratio of strange to nonstrange B meson production to be fs/(fu+fd)=[21.0±3.6(stat) -3.0+3.8(syst)]%. This measurement is the most precise available from hadron collisions to date. Limits on the branching fractions of semileptonic charm meson decays with K1(1270), K1* (1410), and K2*(1430) mesons in the final state are also obtained. ©1999 The American Physical Society.
