Test of an additive diquark spectator model for meson-baryon quasi-two-body reactions
Physical Review D 19:3 (1979) 820-837
Abstract:
An additive diquark model is proposed to relate the forward cross sections of meson-baryon quasi-two-body reactions. The model consists of a quark-diquark structure for baryons combined with additivity of quark-(di)quark amplitudes. Good agreement is found between this model, which contains only one free parameter, and a large body of experimental data for charge-exchange and strangeness-exchange meson-baryon two-body reactions. This is in contrast to the SU(6)-symmetric additive quark model which disagrees violently with the data. © 1979 The American Physical Society.KBAR-K AND PBAR-P OFF-SHELL ANNIHILATIONS FROM K-+P-]LAMBDAL+PIONS AT 4.2 GEV-C

An enhancement at the ΣK threshold (1680) MeV observed in K- p reactions at 4.2 GeV/c
Physics Letters B 80:1-2 (1978) 145-149
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.Ω- produced in K-p reactions at 4.2 GeV/c
