We develop a previously proposed gaugeinvariant method to integrate out an infinite tower of KaluzaKlein (KK) modes of vector and axialvector mesons in a class of models of holographic QCD (HQCD). The HQCD is reduced by our method to
chiral perturbation theory
with
hidden local symmetry
(HLS), having only the lowest KK mode identified as the HLS gauge boson. We take the SakaiSugimoto model as a concrete HQCD, and completely determine the O(p4) terms as well as the O(p2) terms from the DiracBornInfeld part and the anomalyrelated (intrinsicparity odd) gaugeinvariant terms from the ChernSimons part. Effects of higher KK modes are fully included in these terms. To demonstrate the power of our method, we compute momentum dependences of several form factors, such as the pion electromagnetic form factors, and the pi0gamma and omegapi0 transition form factors, compared with experiment, which was not achieved before due to the complication of handling infinite sums. We also study other anomalyrelated quantities like gamma*pi0pi+pi and omegapi0pi+pi vertex functions.
