Abstract

We evaluate the low-energy expansion of the K scattering amplitude to one-loop order in chiral perturbation theory. We predict the pertinent scattering lengths and effective-range parameters beyond the current-algebra values. We compare to the existing data and point towards the need of more accurate experiments.
