Description/Abstract | Using an impact parameter tag to select an enriched sample of Z{sup 0} {yields} b{bar b} events, the authors have measured the difference between the average charged multiplicity of Z{sup 0} {yields} b{bar b} and Z{sup 0} {yields} hadrons to be {bar n}{sub b} - {bar n}{sub had} = 2.24 {+-} 0.30(stat.) {+-} 0.33(syst.) tracks per event. From this, they have derived {bar n}{sub b} - {bar n}{sub uds} = 3.31 {+-} 0.41 {+-} 0.79. Comparing this measurement with those at lower center-of-mass energies, the authors find no evidence that {bar n}{sub b} - {bar n}{sub uds} depends on energy, in agreement with a precise prediction of perturbative QCD. |
