Measurement of b-Quark Fragmentation Fractions in pp[over ] Collisions at sqrt[s]=1.8 TeV. Academic Article uri icon

abstract

  • We have studied the production of B hadrons in 1.8-TeV pp[over ] collisions. We present measurements of the fragmentation fractions, f_{u}, f_{d}, f_{s}, and f_{baryon}, of produced b quarks that yield B^{+}, B^{0}, B_{s}^{0}, and [over ]_{b}^{0} hadrons. Reconstruction of five electron-charm final states yields f_{s}/( f_{u}+f_{d})=0.2130.068 and f_{baryon}/( f_{u}+f_{d})=0.1180.042, assuming f_{u}=f_{d}. If all B hadrons produced in pp[over ] collisions cascade to one of these four hadrons, we determine f_{u}=f_{d}=0.3750.023, f_{s}=0.1600.044, and f_{baryon}=0.0900.029. If we do not assume f_{u}=f_{d}, we find f_{d}/f_{u}=0.840.16.
