Compact Formulas for Tree Amplitudes of Six Partons

TL;DR
This work addresses the computation of tree-level six-parton amplitudes by leveraging extended BCF/BCFW recursion and CSW rules. It derives compact, factorized expressions for non-MHV amplitudes with fermions in both adjoint (gauginos) and fundamental (quarks) representations, and demonstrates their equivalence with conventional field-theory results. By combining these new results with prior lw3 findings, the authors assemble a complete set of six-parton tree amplitudes in compact form. The methods significantly simplify perturbative calculations relevant to jet physics in gauge theories.
Abstract
Compact results are obtained for tree-level non-MHV amplitudes of six fermions and of four fermions and two gluons, by using extended BCF/BCFW rules. Combining with previous results, complete set of tree amplitudes of six partons are now available in compact forms.
