The Four-Loop Planar Amplitude and Cusp Anomalous Dimension in Maximally Supersymmetric Yang-Mills Theory
We present an expression for the leading-color (planar) four-loop four-point amplitude of N = 4 supersymmetric Yang-Mills theory in 4 − 2ǫ dimensions, in terms of eight separate integrals. The expression is based on consistency of unitarity cuts and infrared divergences. We expand the integrals around ǫ = 0, and obtain analytic expressions for the poles from 1/ǫ8 through 1/ǫ4. We give numerical...
متن کاملFour-Loop Cusp Anomalous Dimension From Obstructions
Freddy Cachazo, ∗ Marcus Spradlin, † and Anastasia Volovich ‡ Perimeter Institute for Theoretical Physics, Waterloo, Ontario N2J 2W9, Canada Brown University, Providence, Rhode Island 02912, USA Abstract We introduce a method for extracting the cusp anomalous dimension at L loops from four-gluon amplitudes inN = 4 Yang-Mills without evaluating any integrals that depend on the kinematical invari...
متن کاملAnomalous Transformation in Supersymmetric Yang-Mills Theory
An “anomalous” supersymmetry transformation of the gaugino axial current is given in supersymmetric Yang-Mills theory. The contact term is computed to one-loop order by a gauge-invariant point-splitting procedure. We reexamine the supercurrent anomaly in this method. Work supported in part by NSF Grant Phy 91-08054
متن کاملCusp anomalous dimension in maximally supersymmetric Yang-Mills theory at strong coupling.
We construct an analytical solution to the integral equation which is believed to describe logarithmic growth of the anomalous dimensions of high-spin operators in planar N=4 super Yang-Mills theory and use it to determine the strong coupling expansion of the cusp anomalous dimension.
متن کاملAnomalous dimension of the gluon operator in pure Yang-Mills theory.
We present new one loop calculations that confirm the theorems of Joglekar and Lee on the renormalization of composite operators. We do this by considering physical matrix elements with the operators inserted at non-zero momentum. The resulting IR singularities are regulated dimensionally. We show that the physical matrix element of the BRST exact gauge variant operator which appears in the ene...
