A study of the centrally produced 3pi channel in pp interactions at 450 GeV/c

The WA102 collaboration Barberis, D. ; Beusch, W. ; Binon, F.G. ; et al.
Phys.Lett.B 422 (1998) 399-404, 1998.
Inspire Record 466032 DOI 10.17182/hepdata.41629

The reaction pp -> pf (pi+pi-pi0) ps has been studied at 450 GeV/c in an experiment designed to search for gluonic states. A spin analysis has been performed and the dPT filter applied. The analysis confirms the previous observation that all undisputed qqbar states are suppressed at small dPT. In addition, a clear difference is observed in the production mechanism for the eta and omega.

SIG(C=TOT) denotes the total cross section for each resonance. The variable ABS(PT(P=3)-PT(P=4)) is used as a glueball-QUARK QUARKBAR filter (see F.E.Close and A.Krik, PL 397B, 333 (1997)).

Mass identified particle production in proton anti-proton collisions at s**(1/2) = 300-GeV, 540-GeV, 1000-GeV, and 1800-GeV

The E735 collaboration Alexopoulos, T. ; Allen, C. ; Anderson, E.W. ; et al.
Phys.Rev.D 48 (1993) 984-997, 1993.
Inspire Record 363171 DOI 10.17182/hepdata.22669

The yields and average transverse momenta of pions, kaons, and antiprotons produced at the Fermilab p¯p collider at s=300, 540, 1000, and 1800 GeV are presented and compared with data from the energies reached at the CERN collider. We also present data on the dependence of average transverse momentum 〈pt〉 and particle ratios as a function of charged particle density dNcdη; data for particle densities as high as six times the average value, corresponding to a Bjorken energy density 6 GeV/fm3, are reported. These data are relevant to the search for quark-gluon phase of QCD.

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.
