Jet function with a jet algorithm in soft-collinear effective theory
The jet function for the factorized cross section e{sup +}e{sup -} into dijets is given as a function of the jet invariant mass s and with a generic jet algorithm at O({alpha}{sub s}). We demonstrate the results using the Sterman-Weinberg algorithm and show that the jet function is independent of the energy fraction {beta} of the soft radiation. The anomalous dimension has the same form with and without the cone half-angle {delta}. The dependence of the finite part of the jet function on the cone angle is given.
