Eta and omega Meson Production in Medium-Energy pi+- p and K- p Interactions

The Aachen-Berlin-Bonn-CERN-Cracow-London-Vienna-Warsaw collaboration Bartke, J. ; Kirk, H. ; Kaltwasser, J. ; et al.

The production of η(550) and ω(780) mesons is studied in π ± p interactions at 16 GeV/ c and K − p interactions at 10 and 16 GeV/ c . Cross sections for exclusive channels are presented, and for the π + p data differential cross sections are given for quasi-inclusive production where the η or ω is required to be accompanied by charged particles only. Close similarities are observed between η, ω and also ϱ 0 (770) production in terms of longitudinal and transverse variables. By a rough estimate, the η, ω and ϱ 0 inclusive yields are found to be in the ratio 0.32 : 0.85 : 1, respectively, for 16 GeV/ c π + p collisions. For non-peripheral production we estimate this same ratio to be 0.34 : 0.9 : 1.

Reaction K- p --> Lambda eta from 1.2 to 1.7 GeV/c

Flatte, Stanley M. ; Wohl, Charles G. ;
Phys.Rev. 163 (1967) 1441-1446, 1967.
Inspire Record 52559 DOI 10.17182/hepdata.26566

Total and differential cross sections of the reaction K−p→Λη have been determined for incident K− lab momenta between 1.2 and 1.7 BeVc. No striking resonance formation in the direct channel is seen; in particular, the Y0*(2100) decays not more than 3% via the Λη channel. A prominent forward peak in the differential cross sections indicates some crossed-channel meson-exchange activity. The branching ratio Γ(η→neutrals)Γ(η→π+π−π0) is 3.6±0.6.
