Antinuclei production in heavy ion collisions at CERN SPS.

The NA52 collaboration Arsenescu, R. ; Baglin, C. ; Beck, H.P. ; et al.
Nucl.Phys.A 661 (1999) 177-184, 1999.
Inspire Record 514756 DOI 10.17182/hepdata.36135

Besides the dedicated search for strangelets NA52 measures light (anti)particle and (anti)nuclei production over a wide range of rapidity. Compared to previous runs the statistics has been increased in the 1998 run by more than one order of magnitude for negatively charged objects at different spectrometer rigidities. At a rigidity of −20 GeV/ c we measured 10 6 p , 10 3 d and one 3 He without any centrality requirements. These preliminary results together with previous measurements near central rapidity are discussed in the framework of a thermodynamical and a coalescence model.

Inclusive production of omega mesons at large transverse momenta in pi- Be interactions at 515-GeV/c.

The E706 collaboration Apanasevich, L. ; Bacigalupi, J. ; Baker, W. ; et al.
FERMILAB-PUB-00-054-E, 2000.

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.

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.

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.
