Abstract
Using the helicity formalism, we compute the contribution of a quark-antiquark pair to the tree-level multigluon amplitudes in the high-energy limit. The -pair production is absent in the leading-log formalism, but contributes to the next-to-leading corrections to it, and is, therefore, relevant for the computation of parton-parton scattering in the high-energy limit and of the gluon anomalous dimension at small , at next-to-leading accuracy.
