Measurement of b quark fragmentation fractions in the production of strange and light B mesons in p{ovr p} collisions at {radical ovr s} = 1.8 TeV.
A new technique to measure the ratio of b quark fragmentation fractions in p{ovr p} collisions is described. Using a 70-pb{sup -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 {yields} c{mu}X with c {yields} s{mu} X. By counting the numbers of K*(892){sup 0}, K*(892){sup 1}, and {Phi} (1020) mesons produced in association with these muon pairs, we measure the ratio of strange to nonstrange B meson production to be f{sub s}/(f{sub u} + i > f{sub d}) = [21.0{+-}3.6(stat){sub -3.0}{sup +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 K{sub 1} (1270), K{sub 1}* (1410), and K{sub 2}* (1430) mesons in the final state are also obtained.
