Analysis and interpretation of new low-energy Pi-Pi scattering data
S. Descotes, N. H. Fuchs, L. Girlanda +1
The recently published E865 data on charged K_e4 decays and Pi-Pi phases are reanalyzed to extract values of the two S-wave scattering lengths, of the subthreshold parameters alpha…
The anomalous chiral Lagrangian of order
J. Bijnens, L. Girlanda, P. Talavera
We construct the effective chiral Lagrangian for chiral perturbation theory in the mesonic odd-intrinsic-parity sector at order . The Lagrangian contains 24 in principle measu…
Double chiral logarithms of Generalized Chiral Perturbation Theory for low-energy pi-pi scattering
L. Girlanda
We express the two-massless-flavor Gell-Mann--Oakes--Renner ratio in terms of low-energy pi-pi observables, including the O(p^6) double chiral logarithms of generalized chiral pert…
Eta' Mass and Chiral Symmetry Breaking at Large Nc and Nf
L. Girlanda, J. Stern, P. Talavera
We propose a method for implementing the large-Nc, large-Nf limit of QCD at the effective Lagrangian level. Depending on the value of the ratio Nf/Nc, different patterns of chiral…
