Progress in chiral perturbation theory
G. Ecker
After a short status report on chiral perturbation theory, I review recent progress in determining some of the low-energy couplings by matching the effective theory to QCD. Consequ…

The < S P P > Green function and SU(3) breaking in K_{l3} decays
V. Cirigliano, G. Ecker, M. Eidemuller +3
Using the 1/N_C expansion scheme and truncating the hadronic spectrum to the lowest-lying resonances, we match a meromorphic approximation to the < S P P > Green function onto QCD…
