Abstract
An enhancement in the (∑ K̅) mass spectrum at threshold is observed in K-p interactions at 4.2 GeV/c. It appeats both in the neutral and negative charge states. Corresponding ΛK̅ mass distributions show weak evidence for an effect close to this threshold (~1680 MeV). Although the interpretation of the (∑K ̅) enhancement by itself is ambiguous, a (∑K̅ )-(ΛK̅ ) coupled channel analysis gives results compatible with its interpretation as a new ≡.
