Infrared Limit of Gluon Amplitudes at Strong Coupling
"... In this note, we propose that the infrared structure of gluon amplitudes at strong coupling can be fully extracted from a local consideration near cusps. This is consistent with field theory and correctly reproduces the infrared divergences of the fourgluon In the recent paper [1], Alday and Maldac ..."

All split helicity treelevel gluon amplitudes
, 2006
"... Recently a new recursion relation for treelevel gluon amplitudes in gauge theory has been discovered. We solve this recursion to obtain explicit formulas for the closed set of amplitudes with arbitrarily many positive and negative helicity gluons in a split helicity configuration. The solution admi ..."

The Structure of the BernKosower Integrand for the NGluon Amplitude
"... An ambiguity inherent in the partial integration procedure leading to the BernKosower rules is fixed in a way which preserves the complete permutation symmetry in the scattering states. This leads to a canonical version of the BernKosower representation for the oneloop N  photon/gluon amplitudes, ..."

The hexagon Wilson loop and the BDS ansatz for the sixgluon amplitude, Phys
 Lett. B
"... As a test of the gluon scattering amplitude/Wilson loop duality, we evaluate the hexagonal lightlike Wilson loop at two loops in N = 4 super YangMills theory. We compare its finite part to the BernDixonSmirnov (BDS) conjecture for the finite part of the sixgluon amplitude. We find that the two e ..."

MHV rules for Higgs plus multigluon amplitudes
, 2004
"... We use treelevel perturbation theory to show how nonsupersymmetric oneloop scattering amplitudes for a Higgs boson plus an arbitrary number of partons can be constructed, in the limit of a heavy top quark, from a generalization of the scalar graph approach of Cachazo, Svrček and Witten. The Higgs ..."

. The Higgs boson couples to gluons through a top quark loop which generates, for large mt, a dimension5 operator H tr GµνG µν. This effective interaction leads to amplitudes which cannot be described by the standard MHV rules; for example, amplitudes where all of the gluons have positive helicity. We split
