ABSTRACT: We explore the physics associated with the addition of the Chern-Simons (CS) term in two holographic models, where the strongly coupled QCD appears to be dual to certain five dimensional (5D) weakly coupled gauge theory. Essentially, we work in the chiral limit of QCD with two flavors, and employ holographic correspondence to compute vertex functions and couplings that are induced by the 5D CS term. In particular, we show that the addition of the 5D CS term allows to reproduce the appropriate chiral anomaly of QCD and much more. As an instructive example, we use one of the CS term induced couplings to provide predictions for the f_1 meson photoproduction
