Photoproduction of pi0 omega off protons for E(gamma) < 3-GeV.

The CB-ELSA collaboration Junkersfeld, J. ; Anisovich, A.V. ; Anton, G. ; et al.

Eur.Phys.J.A 31 (2007) 365-372, 2007.

Inspire Record 748502 DOI 10.17182/hepdata.43511

Differential and total cross-sections for photoproduction of gamma proton to proton pi0 omega and gamma proton to Delta+ omega were determined from measurements of the CB-ELSA experiment, performed at the electron accelerator ELSA in Bonn. The measurements covered the photon energy range from the production threshold up to 3GeV.

Charged particle production in S S collisions at 200-GeV/c per nucleon

The WA94 collaboration Andrighetto, A. ; Antinori, F. ; Bayes, A.C. ; et al.

Phys.Lett.B 412 (1997) 148-154, 1997.

Inspire Record 460283 DOI 10.17182/hepdata.28242

Charged particle production in central S-S collisions at 200 GeV/ c per nucleon has been studied by the WA94 experiment at the CERN-SPS. Particle identification has been provided by the Omega RICH, while a silicon telescope in the Omega spectrometer and an array of MultiWire Proportional Chambers have been used to trace particles through the RICH detector. Production ratios and transverse mass spectra for π ± , K ± and p( p ) at central rapidity and p T > 1.3 GeV/ c are presented.

WA97 results on strangeness production in lead lead collisions at 158-A-GeV/c

The WA97 collaboration Andersen, E. ; Andrighetto, A. ; Antinori, F. ; et al.

Nucl.Phys.A 610 (1996) 165C-174C, 1996.

Inspire Record 432744 DOI 10.17182/hepdata.36503

Preliminary results from WA97 measurements on Λ, Ξ and Ω production in lead-lead and proton-lead collisions are presented, along with a comparison of WA97 proton-lead data with previous WA85 proton-tungsten results. The ratio Ω gX seems to be enhanced in lead initiated reactions compared to proton initiated reactions.

Cross-sections of backward proton production in 40-GeV/c pi- (K-, anti-p) A interactions

Antipov, Yu.M. ; Batarin, V.A. ; Bezzubov, V.A. ; et al.

Nucl.Phys.A 536 (1992) 637-647, 1992.

Inspire Record 337176 DOI 10.17182/hepdata.36704

The inclusive cross sections of backward proton production in π − ( K − , p ) -Be, Al, Cu, Pb interactions at 40 GeV/ c are presented. Protons have been detected in the angular range 150°–165° and kinetic energy region 0.1–0.3 GeV. The invariant cross-section ratios for various beam particles are independent of the values of kinetic energy and of the nuclear target type: 〈ƒ K − /ƒ π − 〉= 0.87 ± 0.03 stat ± 0.03 syst , 〈ƒ p /ƒ π − 〉 = 1.82 ± 0.10 stat ± 0.05 syst . The A -dependence of the cross-section slope parameter for A ⩾27 is less than ∼2%.
