Abstract

The real and imaginary parts of the K¯0d scattering length are extracted from the K¯0d mass spectrum obtained from the reaction pp→dK¯0K+ measured recently at the Cooler Synchrotron COSY at Jülich. We extract a new limit on the K−d scattering length, namely Ima⩽1.3 fm and |Rea|⩽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.
