Description:
Author(s): Diogo Boito, Maarten Golterman, Matthias Jamin, Kim Maltman, and Santiago Peris We use results of fits to the OPAL spectral data, obtained from nonstrange hadronic τ decays, to evaluate the difference between the vector and axial current correlators, Π V - A ( Q 2 ). The behavior of Π V - A ( Q 2 ) near Euclidean momentum Q 2 =0 is used to determine the effective low-energy constants L 10 eff an... [Phys. Rev. D 87, 094008] Published Fri May 10, 2013
