Xi (1320) and Xi (1530) Production in $K^- p$ Interactions at 4.2-{GeV}/$c$

The reactions K − p → Ξ 0 − (1320) K 0 + , Ξ − (1320) K + (890), Ξ 0 − (1530) K 0 − and Ξ 0 − (1530) K 0 + (890) are studied at 4.2 GeV/ c incident momentum. The data come from a high-statistics bubble chamber experiment with a sensitivity of ∼ 133 events/ μ b. Total anddifferential cross sections are presented. The results are compared to the SU(3)-related processes K + p → pK + and K + p → pK + (890) in the backward hemisphere. In the forward hemisphere “forbidden” peaks are observed and current ideas about them are discussed.

A search for xi* resonances in k- p interactions at 3.95 gev/c

Nucl.Phys.B 37 (1972) 429-443, 1972.
Inspire Record 75291 DOI 10.17182/hepdata.32965

A 12 event/μb bubble chamber experiment on K − p interactions at 3.95 GeV/ c yielded 1212 events including systems with strangeness S = −2. Results concerning cascade resonances with masses less than 2000 MeV are reported; in particular a determination of the mass and width of the Ξ o 1530 and an interpretation of the mass region (1700–/) 2000) MeV.

Search for xi* Production in K- p Interactions at 2.87-GeV/c

Briefel, E. ; Gourevitch, S.A. ; Kirsch, L. ; et al.
Phys.Rev.D 16 (1977) 2706, 1977.
Inspire Record 118843 DOI 10.17182/hepdata.24494

Evidence is presented for production of Ξ* resonances, decaying into Ξπ, Ξ(1530)π, ΛK¯, and ΣK¯, in K−p interactions at 2.87 Gev/c. The data represent final combined results from a 30-events/μb hydrogen exposure and an 18-events/μb exposure in deuterium designed to study Ξ* production in the mass interval 1.46-2.07 GeV/c2. In addition to Ξ(1820) and Ξ(1940), signals have been observed at masses of 1630 MeV/c2 and 1860 MeV/c2 decaying into Ξ−π+ and YK¯, respectively. Reaction cross sections have been measured for all final states containing two visible signs of strangeness, and for the final states ΛK−K+ and Σ0K−K+.

Reactions K- p --> Xi- K0+ pi+0 between 2210 and 2435 MeV Ecm

We give resonant and production cross-sections for the Ξ*-resonances produced in the reactions Ξ−K+π0 and Ξ−π+K0 for 7 incident-K− momenta between 1.93 and 2.52 GeV/c. A partial-wave analysis gives evidence for the existence of a resonance in theD5-state in this mass region.
