Abstract - We will show how it is possible to implement a chiral symmetry breaking mechanism in soft-wall model of holographic QCD. By perturbing a dilaton potential, we show also that it is possible to reproduce the Operator Product Expansion and the spectrum of the vector-vector and axial-axial correlators in the Large Nc limit. This method provides a nice way to perform the analytic continuation of the OPE and predictions for F_\pi and L_{10} chiral constants.
