The production and decay of the quasi-two-body final states KΔ(1232) and K ∗ (892)N produced in K + d interactions below 1.5 GeV/ c have been studied in a bubble chamber experiment.

Baryon exchange in the reactions k- n ---> y pi- at 3-GeV/c

The SABRE collaboration Barloutaud, R. ; Merrill, D. ; Scheuer, J.C. ; et al.

Inspire Record 68766 DOI 10.17182/hepdata.33717

At 3 GeV/ c , the total and differential cross sections of the reactions K − n → Y π − have been determined for nine S = −1 baryonic states. Backward peaks associated with a dip near u = −0.2 are observed in many cases. They have been interpreted, for the isospin-zero Y-states, in terms of a proton-exchange mechanism. The backward peaks in the reactions K − n → Λπ − and K − n → Σ o π − have been more quantitatively related to the backward π N → N π differential cross sections at the same energy. This comparison leads to the conclusion, that the first reaction is dominated by nucleon exchange, whereas the second one requires a more complex exchange mechanism.

Evidence for b(1220) production in an analysis of the reaction k- d ---> p(s) lambda pi+ pi- pi- pi0 at 3 gev/c

The SABRE collaboration Hoogland, W. ; Kluyver, J.C. ; De Vries, T. ; et al.

Phys.Lett.B 33 (1970) 631-634, 1970.

Inspire Record 69351 DOI 10.17182/hepdata.28535

In an analysis of the reaction K − n →Λ4π at 3 GeV c we find evidence for the production of the B(1220) resonance, mainly decaying in ωπ. For the mass and width we find (1236 ± 15) MeV c 2 and (132±20) MeV c 2 respectively. The cross section for the reaction K − n→ Λ +B(1220) is found to be (102±26) μ b.

Search for exotic resonances in k- d interactions at 3 gev/c

The SABRE collaboration Giacomelli, G. ; Lugaresi-Serra, P. ; Minguzzi-Ranzi, A. ; et al.

Phys.Lett.B 33 (1970) 373-376, 1970.

Inspire Record 63055 DOI 10.17182/hepdata.28726

A systematic search for exotic states produced in K − d interactions at 3 GeV/ c is reported. From the analysis of the mass spectra of strange mesons, non-strange mesons, hyperons with S = −1 and S = −2, upper limits for the production cross sections of exotic resonances may be placed at one or two orders of magnitude smaller than for the production of normal resonances of same strangeness and baryon number.
