Measurement of the b-quark fragmentation function in Z0 decays

We present a measurement of the b-quark inclusive fragmentation function in Z0 decays using a novel kinematic B-hadron energy reconstruction technique. The measurement was performed using 350 000 hadronic Z0 events recorded in the SLD experiment at SLAC between 1997 and 1998. The small and stable SLC beam spot and the charge-coupled-device–based vertex detector were used to reconstruct B-decay vertices with high efficiency and purity, and to …
