Abstract
Based on a phenomenologically successful effective chiral theory of pseudoscalar, vector, and axial-vector mesons, all the coefficients of the chiral perturbation theory are predicted. There is no new adjustable parameter in these predictions. Up to O(m²_q) the formulas of the masses of the pseudoscalar mesons are the same as the ones obtained by ChPT.
