Large-Nc QCD and Pade Approximant Theory

Abstract

In the large-Nc limit of QCD, the chiral expansion of the vacuum polarization at low energies determines the whole function at any arbitrarily large (but finite) energy. This result is an immediate consequence of the Theory of Pade Approximants to Stieltjes functions.
