Worldsheet four-point functions in AdS3/CFT2
We calculate some extremal and non-extremal four-point functions on the sphere of certain chiral primary operators for strings on AdS3 ×S3 × T . The computation is done for small values of the spacetime cross-ratio where global SL(2) and SU(2) descendants may be neglected in the intermediate channel. Ignoring also current algebra descendants, we find that in the non-extremal case the integrated...
متن کاملFrom Spacetime to Worldsheet: Four point correlators
The Schwinger representation gives a systematic procedure for recasting large N field theory amplitudes as integrals over closed string moduli space. This procedure has recently been applied to a class of free field four point functions by Aharony, Komargodski and Razamat, to study the leading terms in the putative worldsheet OPE. Here we observe that the dictionary between Schwinger parameters...
متن کاملOn Four-point Functions in the CFT/AdS Correspondence
We discuss the properties of four-point functions in the context of the correspondence between a classical supergravity theory in the bulk of the Anti de Sitter (AdS) space and quantum conformal field theory (CFT) at the boundary. The contribution to a four-point function from the exchange of a scalar field of arbitrary mass in AdS space is explicitly identified with that of the corresponding o...
متن کاملFour - point functions in N = 2 superconformal field theories
Four-point correlation functions of hypermultiplet bilinear composites are analysed in N = 2 superconformal field theory using the superconformal Ward identities and the analyticity properties of the composite operator superfields. It is shown that the complete amplitude is determined by a single arbitrary function of the two conformal cross-ratios of the space-time variables.
متن کاملGeneral graviton exchange graph for four point functions in the
In this note we explicitly compute the graviton exchange graph for scalar fields with arbitrary conformal dimension ∆ in arbitrary spacetime dimension d. This results in an analytical function in ∆ as well as in d.
