TWO-BODY HYPERCHARGE EXCHANGE REACTIONS IN K- p AND pi+ p INTERACTIONS AT 10-GeV/c AND 16-GeV/c

The Aachen-Berlin-Bonn-CERN-Cracow-London-Vienna collaboration Girtler, P. ; Otter, G. ; Bottcher, H. ; et al.
Nucl.Phys.B 159 (1979) 397, 1979.
Inspire Record 146303 DOI 10.17182/hepdata.34626

Cross-section values or upper limits are presented for twenty-five two-body hypercharge-exchange reactions in K − p and π + p interactions at 10 and 16 GeV/ c . The 16 GeV/ c results are compared with some predictions of line-reversal plus exchange-degenerate Regge poles, of SU(3) and of the additive quark model. Agreement is found in all cases.

Nonstrange Vector Meson Production in K- p Interactions at 4.2-GeV/c

The Amsterdam-CERN-Nijmegen-Oxford collaboration Losty, M.J. ; Holmgren, S.-O. ; Aguilar-Benitez, M. ; et al.
Nucl.Phys.B 133 (1978) 38, 1978.
Inspire Record 121759 DOI 10.17182/hepdata.8294

The vector meson production, hypercharge exchange reactions K − p → ( φ , ω , ϱ ) Λ and ( φ , ϱ ) Σ 0 are studied at 4.2 GeV/ c incident momentum. The data come from a high statistics bubble chamber experiment with a sensitivity of ∼ 120 events/μb. Total and differential cross sections are presented. The vector meson density matrix elements and hyperon polarization are investigated as functions of momentum transfer. Amplitude analyses are performed for all five reactions. The results are compared with duality and quark model predictions, as well as used to test current ideas in two-body phenomenology.

A study of the hypercharge exchange reactions k- p ---> 1- 1/2+ at an incoming momentum of 4.25 gev/c

De Groot, A.J. ; Hodgland, W. ; Jongejans, B. ; et al.
Nucl.Phys.B 74 (1974) 77-101, 1974.
Inspire Record 94650 DOI 10.17182/hepdata.32272

Results are reported of a study of the hypercharge reactions K − p → ωΛ (la), K − p → φΛ (lb), K − p → φ ∑ o (lc), K − p → ϱ o Λ (ld), K − p → ϱ o ∑ o (le), K − p → ϱ − ∑ + (lf) in a 12 events/ub bubble chamber experiment using K − mesons of 4.25 GeV/ c momentum. Total and differential cross sections are presented as well as the density matrix elements of the peripherally produced vector meson and (except for reaction (1f)) the hyperon polarization. For reactions (1a) and (1b) an amplitude analysis is performed. The mass and the width of the ϱ−, φ− and f-meson have been determined.
