AdS interpretation of two - point correlation function of QED February 7 , 2008
نویسنده
چکیده
We have considered the two-point correlation function of QED in worldline formalism. In position space it has been written in terms of heat kernel. This leads to introducing the K 1 (x i) function, which is related with the bulk-to-boundary propagator of massless scalar field and to reveal bulk-to-boundary propagator in the expression of photon polarization operator.

A discussion of the AdS/CFT correspondence in IIB is given in a superspace context. The main emphasis is on the properties of SCFT correlators on the boundary which are studied using harmonic superspace techniques. These techniques provide the easiest way of implementing the superconformal Ward identities. The Ward identities, together with an-alyticity, can be used to give a compelling argumen...
متن کاملStrings in AdS 3 and the SL ( 2 , R ) WZW Model . Part 3 : Correlation Functions
We consider correlation functions for string theory on AdS 3. We analyze their singu-larities and we provide a physical interpretation for them. We explain which worldsheet correlation functions have a sensible physical interpretation in terms of the boundary theory. We consider the operator product expansion of the four point function and we find that it factorizes only if a certain condition ...
متن کاملRecursive Graphical Solution of Closed Schwinger-Dyson Equations in φ-Theory – Part1: Generation of Connected and One-Particle Irreducible Feynman Diagrams
Recently, it has been shown that the Schwinger-Dyson equations of QED can be closed in a certain functionalanalytic sense [8]. Using functional derivatives with respect to the free propagators and the interaction [8–14] two closed sets of equations were derived. The first one involves the connected electron and two-point function as well as the connected three-point function, whereas the second...

This paper elaborates on the bulk/boundary relation between negative cosmological constant 3D gravity and Liouville field theory (LFT). We develop an interpretation of LFT non-normalizable states in terms of particles moving in the bulk. This interpretation is suggested by the fact that “heavy” vertex operators of LFT create conical singularities and thus should correspond to point particles mo...
متن کاملLight Fermion Finite Mass Effects in Non-relativistic Bound States
We present analytic expressions for the vacuum polarization effects due to a light fermion with finite mass in the binding energy and in the wave function at the origin of QED and (weak coupling) QCD non-relativistic bound states. Applications to exotic atoms, Υ(1s) and tt̄ production near threshold are briefly discussed. Preprint submitted to Elsevier Preprint 7 February 2008
