Corrections to the StermanWeinberg jet formula

The fraction of hadronic final states from e+e- annihilation consisting of two jets is calculated exactly to lowest order in QCD perturbation theory. This improves the Sterman-Weinberg expression increasing its range of applicability and may allow for detailed quantitative tests of QCD at feasible experimental energies.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23624/1/0000587.pd
