- Abstract:
- An enhancement in the (ΣK) 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 ΛK mass distributions show weak evidence for an effect close to this threshold (∼1680 MeV). Although the interpretation of the (ΣK) enhancement by itself is ambiguous, a (ΣK)-(ΛK) coupled channel analysis gives results compatible with its interpretation as a new Ξ*. © 1978.
