Quark mass effects in QCD jets

Abstract

We present the calculation of the decay width of the Z-boson into three jets including complete quark mass effects to second order in the strong coupling constant. The study is done for different jet clustering algorithms such as EM, JADE, E and DURHAM. Because three-jet observables are very sensitive to the quark mass we consider the possibility of extracting the bottom quark mass from LEP data.
