Chiral meson physics at two loops

• 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 ππ, πK scattering as well as the determination of Vus and K13 decays
