Isospin violation in pion-kaon scattering
Abstract
We consider strong and electromagnetic isospin violation in near-threshold pion-kaon scattering. At tree level, such effects are small for all physical channels. We work out the complete one-loop corrections to the process pi- K+ -> pi0 K0. They come out rather small. We also show that the corresponding radiative cross section is highly suppressed at threshold.
