The Asymptotic Spectrum of the N = 4 Super Yang - Mills Spin Chain
In this paper we discuss the asymptotic spectrum of the spin chain description of planar N = 4 SUSY Yang-Mills. The states appearing in the spectrum belong to irreducible representations of the unbroken supersymmetry SU(2|2)×SU(2|2) with non-trivial extra central extensions. The elementary magnon corresponds to the bifundamental representation while boundstates of Q magnons form a certain short...
متن کاملA Novel Long - Range Spin Chain and Planar N = 4 Super Yang - Mills
We probe the long-range spin chain approach to planar N = 4 gauge theory at high loop order. A recently employed hyperbolic spin chain invented by Inozemtsev is suitable for the su(2) subsector of the state space up to three loops, but ceases to exhibit the conjectured thermodynamic scaling properties at higher orders. We indicate how this may be bypassed while nevertheless preserving integrabi...
متن کاملInformation on the Super Yang - Mills Spectrum
We investigate the spectrum of the lightest states of N = 1 Super Yang-Mills. We first study the spectrum using the recently extended Veneziano Yankielowicz theory containing also the glueball states besides the gluinoball ones. Using a simple Kähler term we show that within the effective Lagrangian approach one can accommodate either the possibility in which the glueballs are heavier or lighte...
متن کاملDeformation of N = 4 Super Yang - Mills Theory in
We study deformation of N = 4 super Yang-Mills theory from type IIB superstrings with D3-branes in the constant R-R background. We compute disk amplitudes with one graviphoton vertex operator and investigate the zero-slope limit of the amplitudes. We obtain the effective action deformed by the graviphoton background, which contains the one defined in non(anti)commutative N = 1 superspace as spe...
متن کاملInfrared Stability of N = 4 Super Yang - Mills
We study the infrared perturbative properties of a class of non supersymmetric gauge theories with the same field content of N = 4 Super YangMills and we show that the N = 4 supersymmetric model represents an IR unstable fixed point for the renormalization group equations.
