QCD condensates from tau-decay data: A functional approach
arXiv:hep-ph/0312212 · doi:10.1016/j.physletb.2004.06.046
Abstract
We study a functional method to extract the V-A condensate of dimension 6 from a comparison of tau-decay data with the asymptotic space-like QCD prediction. Our result is in agreement within errors with that from conventional analyses based on finite energy sum rules.
