title: Tests of Large N(c) QCD from Hadronic tau Decay.
abstract: We use the ALEPH Collaboration data on vector and axial-vector spectral functions to test simple duality properties of QCD in the large N(c) limit, which emerge in the approximation of a minimal hadronic ansatz of a spectrum of narrow states. These duality properties relate the short- and long-distance behaviors of specific correlation functions, which are order parameters of spontaneous chiral symmetry breaking, in a way that we find well supported by the data.
