From hadronic tau decays to the chiral couplings L_10 and C_87
M. Gonzalez-Alonso, A. Pich, J. Prades
A sum rule analysis of the hadronic tau-decay data can be used to determine the low-energy constants L10(mu) and C87(mu). These constants are QCD chiral-order parameters, which app…
Determination of the Chiral Couplings L_10 and C_87 from Semileptonic Tau Decays
Martin Gonzalez-Alonso, Antonio Pich, Joaquim Prades
Using recent precise hadronic tau-decay data on the V-A spectral function, and general properties of QCD such as analyticity, the operator product expansion and chiral perturbation…
