Chiral Meson Physics at Two Loops

Abstract

An overview of Chiral Perturbation Theory calculations in the mesonic sector at the two Loop level is given. Discussed in some detail are the partially quenched case relevant for lattice QCD, the general fitting procedures and $\pi \pi$,$\pi K$ scattering as well as the determination of $V_{us}$ and $K_{\ell 3}$ decays.
