Abstract

The real and imaginary parts of the K⁰ d scattering length are extracted from the K⁰ d mass spectrum obtained from the reaction pp → d K⁰ K⁺ measured recently at the Cooler Synchrotron COSY at Jülich. We extract a new limit on the K^- d scattering length, namely Im a ≤ 1.3 fm and |Re a| ≤ 1.3 fm. The limit for the imaginary part of the K^- d scattering length is supported by data on the total K^- d cross sections.
