From Free Fields to AdS
Free N = 4 Super Yang-Mills theory (in the large N limit) is dual to an, as yet, intractable closed string theory on AdS5 × S. We aim to implement open-closed string duality in this system and thereby recast the free field correlation functions as amplitudes in AdS. The basic strategy is to implement this duality directly on planar field theory correlation functions in the worldline (or first q...
متن کاملFrom Free Fields to AdS – III
In previous work we have shown that large N field theory amplitudes, in Schwinger parametrised form, can be organised into integrals over the stringy moduli space Mg,n × R +. Here we flesh this out into a concrete implementation of open-closed string duality. In particular, we propose that the closed string worldsheet is reconstructed from the unique Strebel quadratic differential that can be a...
متن کاملFrom Free Fields to AdS – II
We continue with the program of hep-th/0308184 to implement open-closed string duality on free gauge field theory (in the large N limit). In this paper we consider correlators such as 〈 ∏n i=1 TrΦ i(xi)〉. The Schwinger parametrisation of this n-point function exhibits a partial gluing up into a set of basic skeleton graphs. We argue that the moduli space of the planar skeleton graphs is exactly...
متن کاملChiral Dynamics From AdS Space
We study the low energy dynamics of pions in a gravity dual of chiral symmetry breaking. The string theory construction consists of a probe D7 brane in the Constable Myers non-supersymmetric background, which has been shown to describe chiral symmetry breaking in the pattern of QCD. We expand the D7 brane’s Dirac Born Infeld action for fluctuations that correspond to the Goldstone mode and show...
متن کاملGeneralized free fields and the AdS-CFT correspondence
Motivated by structural issues in the AdS-CFT correspondence, the theory of generalized free fields is reconsidered. A stress-energy tensor for the generalized free field is constructed as a limit of Wightman fields. Although this limit is singular, it fulfils the requirements of a conserved local density for the Poincaré generators. An explicit “holographic” formula relating the Klein-Gordon f...
