Isospin Breaking in Low-Energy Charged Pion and Kaon Elastic Scattering
A. Nehme
Abstract
We use chiral perturbation theory to evaluate the scattering amplitude for the process Pi+ K- to Pi+ K- at leading and next-to-leading orders in the chiral counting and in the presence of isospin breaking effects. We also discuss the influence of the latter on the combination of the S-wave Pi K scattering lengths which is relevant for the 2S - 2P energy levels shift of K Pi atoms.
