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(+) --> pi(0)K(0). They come out rather small. We also show that the corresponding radiative cross section is highly suppressed at threshold. (C) 2002 Elsevier Science B.V. All rights reserved.
