Low-energy constants and condensates from the V-A spectrum

Abstract

We present an analysis of the isospin-one V-A correlator based on our successful simultaneous description of the OPAL V and A non-strange tau spectral data. We discuss the values obtained for the Chiral Perturbation Theory low-energy constants L_10 and C_87 as well as the dimension-six and eight condensates and compare them with those in the literature.
