Inclusive production of strange particles p anti-p collisions at s**(1/2) = 630-GeV with UA1

Bocquet, G. ; Norton, A. ; Wang, H.Q. ; et al.
Phys.Lett.B 366 (1996) 441-446, 1996.
Inspire Record 403648 DOI 10.17182/hepdata.48059

We have analysed a sample of 2.36 million minimum bias events produced in p p collisions at s =630 GeV in the UA1 experiment at the CERN Sp p S collider. We have studied the production of K S 0 , Λ and Λ particles with transverse momenta ( p t ) up to 7 GeV/c and K ± up to 2 GeV/c. The kaon data are compared with a recent QCD prediction and are found to be in good agreement. The < p t > for K S 0 , Λ and Λ is seen to increase as a function of the charged particle multiplicity and is compared with charged particle production.

A Study of particle ratios and strangeness suppression in p anti-p collisions at s**(1/2) = 630-GeV with UA1

Bocquet, G. ; Norton, A. ; Wang, H.Q. ; et al.
Phys.Lett.B 366 (1996) 447-450, 1996.

From a sample of 2.36 million minimum bias events produced in p p collisions at s =630 GeV in the UA1 experiment and from other published data at the CERN S p p S collider we have estimated the relative production of π ± , π 0 , K ± , K S 0 , Λ, Λ , p and p . We obtain a meson over baryon ratio M B = 6.4 ± 1.1 . From the K S 0 π ± ratio we measure the strangeness suppression factor λ = 0.29 ± 0.02 ± 0.01 which, combining with other available data provides a new world average of 0.29 ± 0.015. Both the K S 0 π ± ratio and the strangeness suppression factor λ as a function of s are investigated, and an extrapolation to the LHC energy is performed.

Results from E735 at the tevatron proton - anti-proton collider with s**(1/2) = 1.8-TeV

The E735 collaboration Lindsey, Clark S. ; Alexopoulos, T. ; Allen, C. ; et al.
Nucl.Phys.A 544 (1992) 343-356, 1992.
Inspire Record 322633 DOI 10.17182/hepdata.43062

Experiment E735 searched for evidence of the transition to quark-gluon plasma in p p collisions at √ s = 1.8 TeV. Using data from a high statistics run in 1988–1989, results are presented on multiplicity distributions, hyperon and phi production, and Bose-Einstein correlations. Some data were also taken at lower collision energies and results will be compared to previous experiments.

Production of neutral strange particles in p Ar, p Xe and anti-p Xe collisions at 200-GeV

Derado, I. ; Kadija, K. ; Malecki, M. ; et al.
Z.Phys.C 50 (1991) 31-36, 1991.
Inspire Record 28958 DOI 10.17182/hepdata.15007

The production of neutral strange particles (K0, Λ) inp Ar,pXe and\(\bar p\)Xe collisions at 200 GeV is investigated in the NA5 experiment using a streamer chamber at the CERN SPS. Results are presented on inclusive cross sections, average multiplicities, and on rapidity and transverse momentum distributions of neutral strange particles.
