Gravity dual of the chiral anomaly

We study effects associated with the chiral anomaly for a cascading $\mathrm{SU}(N+M)\mathrm{}\times \mathrm{SU}\left(N\right)\mathrm{}$ gauge theory using gauge/gravity duality. In the gravity dual the anomaly is a classical feature of the supergravity solution, and the breaking of the $U\left(1\right)\mathrm{}\hspace{0.5em}R$ symmetry down to ${\mathbf{Z}}_{2M}$ proceeds via the Higgs mechanism.
