$\tau$ spectral functions, QCD applications and chiral sum rules
An analysis based on 124 000 selected tau pairs recorded by the ALEPH detector at LEP provides the vector (V) and axial-vector (A) spectral functions of hadronic tau decays. The spectral functions of the dominant two- and four-pion vector tau decay modes are compared to published results of e/sup +/...
