ππscattering at low energy: status report

J. Gasser

I discuss the status of ongoing work to determine numerically the elastic $π π$ scattering amplitude at order $p^{6}$ in the framework of chiral perturbation theory.

Two--loop integrals in chiral perturbation theory

J. Gasser, M. E. Sainio

We consider chiral perturbation theory in the meson sector at order $E^{6}$ . In the terminology of the external field technique, the two--loop graphs so generated are of the sunset t…
