Title: Factorization of the connected prescription for Yang-Mills amplitudes

Abstract

We examine factorization in the connected prescription of Yang-Mills amplitudes. The multiparticle pole is interpreted as coming from representing delta functions as meromorphic functions. However, a naive evaluation does not give a correct result. We give a simple prescription for the integration contour which does give the correct result. We verify this prescription for a family of gauge-fixing conditions.

  • We investigate the renormalization properties of Yang-Mills theories in axial gauges within the generalized Leibbrandt-Mandelstam prescription which unifies all axial gauges, including the light-cone gauge, within one uniform prescription. We calculate the divergent part of the gluon self-energy in a planar-type gauge fixing. All known results on the planar gauge and on the light-cone gauge are recovered as special cases. At variance to the light-cone gauge for n/sup 2/not =0 only the S matrix, but not the Green's functions, can be renormalized by local counterterms.
  • In this paper, we study the apparent discrepancy between Feynman diagrams and the eikonal formulas, and the apparent paradox between the eikonal formulas and the s-u crossing symmetry. We analyze the generalized leading-term approximation (GLA), which generates the terms of the eikonal formulas from Feynman diagrams. This analysis is done through using the techniques of decomposing diagrammatically the isospin factors (or group-theoretical weights in general) of Feynman diagrams. As a result, we modify the GLA into a generalized complex leading-term approximation. We calculate, with this new formalism, the high-energy limit (s..-->..infinity with t fixed) of the vector-meson--vector-meson elastic amplitude ofmore » a Yang-Mills theory with SU(2) symmetry through tenth perturbative order. With this new method, we resolve the apparent discrepancy and paradox mentioned above. This method is generalizable to other non-Abelian gauge theories.« less
  • We compute the leading-color (planar) three-loop four-point amplitude of N = 4 supersymmetric Yang-Mills theory in 4 - 2{epsilon} dimensions, as a Laurent expansion about {epsilon} = 0 including the finite terms. The amplitude was constructed previously via the unitarity method, in terms of two Feynman loop integrals, one of which has been evaluated already. Here we use the Mellin-Barnes integration technique to evaluate the Laurent expansion of the second integral. Strikingly, the amplitude is expressible, through the finite terms, in terms of the corresponding one- and two-loop amplitudes, which provides strong evidence for a previous conjecture that higher-loop planarmore » N = 4 amplitudes have an iterative structure. The infrared singularities of the amplitude agree with the predictions of Sterman and Tejeda-Yeomans based on resummation. Based on the four-point result and the exponentiation of infrared singularities, we give an exponentiated ansatz for the maximally helicity-violating n-point amplitudes to all loop orders. The 1/{epsilon}{sup 2} pole in the four-point amplitude determines the soft, or cusp, anomalous dimension at three loops in N = 4 supersymmetric Yang-Mills theory. The result confirms a prediction by Kotikov, Lipatov, Onishchenko and Velizhanin, which utilizes the leading-twist anomalous dimensions in QCD computed by Moch, Vermaseren and Vogt. Following similar logic, we are able to predict a term in the three-loop quark and gluon form factors in QCD.« less
  • Asymptotic forms of the eighth-order amplitudes for both fermion-fermion scattering and vector-vector scattering are given in the Yang-Mills theory with an isospin-1/2 Higgs boson, in the limit s $Yields$ infinity with t fixed. (AIP)
  • Using the N = 4 super-Yang-Mills theory softly broken by supersymmetric N = 1 mass terms for the matter superfields, the authors compute the one-loop chiral + chiral {r arrow} antichiral + antichiral scattering amplitude directly in superspace. By suitable choices of the mass parameters, one can endow the model with a heirachy of light and heavy particles, and the decoupling of the heavy sector from the light-light physical amplitude is studies. The authors also analyze the high-energy limit of the cross-section for a two physical scalar scattering and find a (logs) behavior, which then respects the Froissart bound.
