Jet rates in electron-positron annihilation at O(alpha_s^3) in QCD.

Gehrmann-De Ridder, A. and Gehrmann, T. and Glover, E.W.N. and Heinrich, G. (2008) 'Jet rates in electron-positron annihilation at O(alpha_s^3) in QCD.', Physical review letters., 100 (17). p. 172001.

Abstract

We compute production rates for two, three, four, and five jets in electron-positron annihilation at the third order in the QCD coupling constant. At this order, three-jet production is described to next-to-next-to-leading order in perturbation theory while the two-jet rate is obtained at next-to-next-to-next-to-leading order. Our results yield an improved perturbative description of the dependence of jet multiplicity on the jet resolution parameter ycut, particularly at small values of ycut.
