Next-to-Leading Order QCD Corrections to Three-Jet Cross Sections with Massive Quarks
Abstract
We calculate the cross section for e+ e- annihilation into three jets for massive quarks at next-to-leading order in perturbative QCD, both on and off the Z resonance. Our computation allows the implementation of any jet clustering algorithm. We give results for the three-jet cross section involving b quarks for the JADE and Durham algorithm at c.m. energies s = mZ. We also discuss a three-jet observable that is sensitive to the mass of the b quark.
