1/N Corrections to Anomalies and the AdS/CFT Correspondence for Orientifolded N = 2 Orbifold and N=1 Conifold Models
Abstract
We show that for a large class of d=4 N =2 conformal field theories the 1/N correction to the chiral anomaly of the U(1) Rcurrent can be shown to arise from the D7branes present in the dual orientifolded orbifold string theories, generalizing a result in the literature for the simplest case. We also study the U(1)_{R} anomaly for d=4 N=1 conformal field theories that arise from orientifolds of the conifold. We find agreement between the field and stringtheoretic calculations, confirming a prediction of the AdS/CFT correspondence at order 1/N for string theories on AdS_{5} × T^{11}/Z_{2}.
