On two-point correlation functions in AdS/QCD
arXiv:0801.4215 · doi:10.1103/PhysRevD.77.126014
Abstract
In this paper we study the chiral symmetry breaking in the hard wall AdS/QCD model. We solve the equations of motion up to the second order at large momentum and obtain the first few terms in the expansion of the "left-right" correlator, which is the measure of symmetry breaking. We study the dependence on AdS radius to get the result as the series in t'Hooft constant.
