| dc.description.abstract | We consider the possibility of extracting the bottom quark mass from LEP data. The inclusive decay rate for $\zbb +\cdots$ is obtained at order $\as$ by summing up the one-loop two-parton decay rate to the tree-level three-parton rate. We calculate the decay width of the Z-boson into two and three jets containing the b-quark including complete quark mass effects. In particular, we give analytic results for a slight modification of the JADE clustering algorithm. We also study the angular distribution with respect to the angle formed between the gluon and the quark jets, which has a strong dependence on the quark mass. The impact of higher order QCD corrections on these observables is briefly discussed. Finally, we present numerical results for some popular jet-clustering algorithms and show that, indeed, these three-jet observables are very sensitive to the b-quark mass and well suited for its determination at LEP. | |
