The full four-loop cusp anomalous dimension in N$$ \mathcal{N} $$ = 4 super Yang-Mills and QCD
Abstract We present the complete formula for the cusp anomalous dimension at four loops in QCD and in maximally supersymmetric Yang-Mills. In the latter theory it is given by Γcusp,Aαs4=−αsNπ473π620160+ζ328+1N231π65040+9ζ324.$$ {\left.{\Gamma}_{\mathrm{cusp},\mathrm{A}}\right|}_{\alpha_s^4}=-{\le...
