We present results on the production of omega mesons at high transverse momenta in pi^-Be interactions at 515 GeV/c. The data span the kinematic range 3.5 < p_T < 8 GeV/c. We compare the measured cross section with expectations from Monte Carlo QCD generators. The relative yield of omega to pi^0 mesons is used to extract the ratio of vector to pseudoscalar meson production for the first generation of quarks.

Anti-nuclei production in Pb + Pb collisions at 158-A/GeV/c

The NA52 (NEWMASS) collaboration Appelquist, G. ; Baglin, C. ; Beringer, J. ; et al.
Phys.Lett.B 376 (1996) 245-250, 1996.
Inspire Record 40550 DOI 10.17182/hepdata.50119

We investigate antinuclei production in Pb + Pb interactions at 158 GeV/ c per nucleon at zero degree production angle. We quote invariant differential production cross sections for antiprotons and antideuterons. The corresponding antideuteron to antiproton ratio at midrapidity is 4.2 · 10 −4 . One antihelium-3 nucleus was observed. The results are discussed in the framework of a simple coalescence model.

Strangelet search and antinuclei production studies in Pb + Pb collisions

The NA52 (NEWMASS) collaboration Ambrosini, G. ; Appelquist, G. ; Arsenescu, R. ; et al.
Nucl.Phys.A 610 (1996) 306C-316C, 1996.
Inspire Record 432734 DOI 10.17182/hepdata.36512

We searched for long-lived strange quark matter particles, so-called strangelets , and studied particle and antiparticle production in Pb + Pb collisions at 158 GeV/ c per nucleon at zero degree production angle. We give upper limits for the production of strangelets covering a mass to charge ratio up to 120 GeV/ c 2 and lifetimes t lab > 1.2 μ s and plot invariant differential production cross sections as a function of rapidity for a variety of particles.

Inclusive electroproduction of forward protons from neutron and proton targets

Bebek, C.J. ; Brown, C.N. ; Herzlinger, M. ; et al.
Phys.Rev.Lett. 34 (1975) 1115, 1975.
Inspire Record 98990 DOI 10.17182/hepdata.21921

We report new measurements of the inclusive electroproduction of forward protons carried out at the Wilson Synchrotron Laboratory at Cornell University. Data were taken with deuterium at the (W, Q2) points (2.15 GeV, 1.2 GeV2), (2.15, 4.0), and (3.11, 1.2); data were taken with hydrogen at these points and at the points (2.15, 2.0), (2.67, 3.3), and (3.11, 1.7). The invariant structure function is presented in terms of W, Q2, and ω.

Production of high transverse momentum particles in p p collisions in the central region at the CERN ISR

The British-Scandinavian ISR collaboration Alper, B. ; Boggild, H. ; Jarlskog, G. ; et al.
Phys.Lett.B 44 (1973) 521-526, 1973.
Inspire Record 85256 DOI 10.17182/hepdata.28095

The inclusive production al all charged particles of transverse momentum p T between 1.5 and 4.4 GeV/ c at centre of mass angles 90° and 59.4° from p-p-collisions with √ s = 44 and 53 GeV has been measured. No strong energy dependence is observed for these transverse momenta.
