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+.

K- p Cross-Sections Between 1.1-GeV/c and 1.4-GeV/c

Griselin, J. ; Givernaud, A. ; Barloutaud, R. ; et al.
Nucl.Phys.B 93 (1975) 189-216, 1975.
Inspire Record 99412 DOI 10.17182/hepdata.6708

K − p reactions have been studied at 13 different incident momenta between 1138 and 1434 MeV/ c . This interval corresponds to a mass of the K − p system varying from 1858 to 1993 MeV. About 300 000 photographs were taken in the 81 cm Saclay hydrogen bubble chamber exposed to a separated K − beam at the CERN proton-synchrotron. A total of about 44 000 events were analyzed, from which partial and differential cross sections were determined. Polarizations were obtained for the two-body reactions where the decay of the Λ or Σ hyperon allowed their measurement. Data for the two-body channels are presented here as well as for the main quasi-two-body reactions.

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

Badier, J. ; Barrelet, E. ; Charlton, G.R. ; et al.
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.

We present the results on total channel cross-sections obtained in the Saclay 180 l HBC exposed to a separated K− beam at Nimrod. The cross-sections for each channel are given at 13 incident K− momenta between 1.26 and 1.84 GeV/c.
