Perturbative Super - Yang - Mills from the Topological AdS 5 × S 5 Sigma Model
نویسنده
چکیده
A topological sigma model based on the pure spinor formalism was recently proposed for the small radius limit of the AdS5 × S 5 superstring. Physical states in this model can be constructed by connecting holes on the worldsheet with Wilson lines of the worldsheet gauge field. The contribution of these states to the topological amplitude is claimed to reproduce the usual Feynman diagram expansion of gauge-invariant super-Yang-Mills correlation functions.

A New Limit of the AdS 5 × S 5 Sigma Model
Using the pure spinor formalism, a quantizable sigma model has been constructed for the superstring in an AdS5 × S 5 background with manifest PSU(2, 2|4) invariance. The PSU(2, 2|4) metric gAB has both vector components gab and spinor components gαβ, and in the limit where the spinor components gαβ are taken to infinity, the AdS5 × S 5 sigma model reduces to the worldsheet action in a flat back...
متن کاملThe Bethe Ansatz for Z S Orbifolds of N = 4 Super Yang - Mills Theory
Worldsheet techniques can be used to argue for the integrability of string theory on AdS 5 × S 5 /Z S , which is dual to the strongly coupled Z S-orbifold of N = 4 SYM. We analyze the integrability of these field theories in the perturbative regime and construct the relevant Bethe equations.
متن کاملWorldsheet Scattering in AdS 5 × S 5
We calculate the S-matrix in the gauge-fixed sigma-model on AdS 5 × S 5 to the leading order in perturbation theory, and analyze how supersymmetry is realized on the scattering states. A mild nonlocality of the supercharges implies that their action on multi-particle states does not follow the Leibniz rule, which is replaced by a nontrivial coproduct. The plane wave symmetry algebra is thus nat...
متن کاملIntegrability and non-perturbative effects in the AdS/CFT correspondence
We present a non-perturbative resummation of the asymptotic strong-coupling expansion for the dressing phase factor of the AdS5 × S string S-matrix. The non-perturbative resummation provides a general form for the coefficients in the weak-coupling expansion, in agreement with crossing symmetry and transcendentality. The ambiguities of the non-perturbative prescription are discussed together wit...
متن کاملSelfduality and Chern–Simons Theory
We propose a relation between the operator of S-duality (of N = 4 super Yang–Mills theory in 3+1D) and a topological theory in one dimension lower. We construct the topological theory by compactifying N = 4 super Yang–Mills on S with an S-duality and R-symmetry twist. The S-duality twist requires a selfdual coupling constant. We argue that for a sufficiently low rank of the gauge group the thre...
