Abstract:

Using a sample of 4.7 fb-1 integrated luminosity accumulated with the CLEO-II detector at the Cornell Electron Storage Ring (CESR), we have measured the ratios of the branching fractions B(Ï„-→K-h+Ï€-ν Ï„)/µþ(Ï„-→h-h+h -ντ)=(5.16±0.20±0.50) × 10-2, B(Ï„-→K-h+Ï€-Ï€ 0ντ)/µþ(Ï„- →h-h+h-Ï€0ν Ï„)=(2.54±0.44±0.39) × 10-2, B(Ï„-→K-K+Ï€-ν Ï„)/µþ(Ï„-→h-h+h -ντ)=(1.52±0.14 ±0.29) × 10-2, and the upper limit B(Ï„-→K-K+Ï€-Ï€ 0ντ)/µþ(Ï„-→h-h +h-Ï€0ντ)<0.0154 at 95% C.L. Coupled with additional experimental information, we use our results to extract information on the structure of three-prong tau decays to charged kaons. ©1999 The American Physical Society.

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.
