Determination of the K̄ 0 d scattering length from the reaction pp → dK̄ 0 K +

Abstract

The real and imaginary parts of the ¯ K 0 d scattering length are extracted from the ¯ K 0 d mass spectrum obtained from the reaction pp→d ¯ K 0 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… (More)
