## A Gravity Dual of the Chiral Anomaly

## Abstract

Supersymmetric quantum field theories often possess a continuous
R-symmetry which is broken quantum mechanically, through instanton
effects. I will discuss this symmetry breaking for a particular QFT, in
the context of gauge/gravity duality. The QFT has N=1 supersymmetry,
gauge group SU(N) x SU(N+M) and bifundamental matter fields, and is dual
to Type IIB string theory on a warped deformed conifold. In the gravity
dual, the R-symmetry is spontaneously broken, and there is no need to
appeal to instantons.
