摘要：

We present results of a recent study of the structure of excited pions within a chiral holographic model for QCD. In particular, we prove that the leptonic decay constants of the excited states of the pion vanish in the chiral limit when chiral symmetry is dynamically broken. Comparisons are made with corresponding results obtained in light-front holography.
