Theoretical progress on cusp effect and Kl4 decays
J. Gasser
The cusp effect in K \to 3πand data on K_e4 decays allow one to extract experimental information on the elastic ππscattering amplitude near threshold, and to confront the outcome o…
Chiral perturbation theory
J. Gasser
I present an outline of chiral perturbation theory and discuss some recent developments in the field.
The one-loop functional as a Berezinian
H. Neufeld, J. Gasser, G. Ecker
We employ notions familiar from supersymmetry for constructing the one-loop functional of general quantum field theories with bosons and fermions (spin < 1). To demonstrate the adv…
Aspects of Chiral Dynamics
J. Gasser
I discuss several topics in chiral perturbation theory - in particular, I recall pecularities of the chiral expansion in the baryon sector.
Pion-pion scattering at low energy
J. Bijnens, G. Colangelo, G. Ecker +2
We present technical details of the evaluation of the elastic pi-pi scattering amplitude to two loops in chiral perturbation theory. In particular, we elaborate on the renormalizat…
Chiral Perturbation Theory
Johan Bijnens
A short overview of the current state of Chiral Perturbation Theory is given. This includes a description of the basic assumptions, the usefulness of the external field method is e…
