Origin of dressing phase in N = 4 Super Yang – Mills
We derive the phase factor proposed by Beisert, Eden and Staudacher for the Smatrix of planar N = 4 Super Yang–Mills, from the all-loop Bethe ansatz equations without the dressing factor. We identify a configuration of the Bethe roots, from which the closed integral formula of the phase factor is reproduced in the thermodynamic limit. This suggests that our configuration describes the “physical...
متن کاملPhase Transition in Yang - Mills Theory For
We infer the existence of a phase transition in pure non-Abelian gauge theories at zero temperature for 0 near IT. Our analysis assumes that instantons are responsible for the onset of the deviation from perturbative behavior in the theory. We show that this leads to a ._ weak coupling zero of the E-function for 8 near IT, implying the loss of confinement. Submitted to Physical Review D (Commen...
متن کاملThe 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 کاملLoop Equation in Two-dimensional Noncommutative Yang-Mills Theory
The classical analysis of Kazakov and Kostov of the Makeenko-Migdal loop equation in two-dimensional gauge theory leads to usual partial differential equations with respect to the areas of windows formed by the loop. We extend this treatment to the case of U(N) Yang-Mills defined on the noncommutative plane. We deal with all the subtleties which arise in their two-dimensional geometric procedur...
متن کاملBeta-functions in Yang-Mills Theory and Wilson-Loop
The renormalization group equations of the Yang-Mills theory are examined in the non-critical string theory according to the framework of the holography. Under a simple ansatz for the tachyon, we could find several interesting solutions which are classified by the value of the tachyon potential at the vacuum. We show two typical, asymptotic-free solutions which are different in their infrared b...
