Anti-proton production and anti-deuteron production limits in relativistic heavy ion collisions from BNL experiment 864

The E864 collaboration Armstrong, T.A. ; Barish, K.N. ; Batsoulli, S. ; et al.
Phys.Rev. C59 (1999) 2699-2712, 1999.
Inspire Record 478873 DOI 10.17182/hepdata.31371

We present results from Experiment 864 for antiproton production and antideuteron limits in Au + Pb collisions at 11.5 GeV/c per nucleon. We have measured invariant multiplicities for antiprotons for rapidities 1.4<y<2.4 at low transverse momentum as a function of collision geometry. When compared with the results from Experiment 878 our measurements suggest a significant contribution to the measured antiproton yield from the decay of strange antibaryons. We have also searched for antideuterons and see no statistically significant signal. Thus, we set upper limits on the production at approximately 3 x 10^{-7} per 10% highest multiplicity Au + Pb interaction.

Centrality dependence of pi+ / pi-, K+ / K-, p and anti-p production from s(NN)**(1/2) = 13-=GeV Au+Au collisions at RHIC

The PHENIX collaboration Adcox, K. ; Adler, S.S. ; Ajitanand, N.N. ; et al.
Phys.Rev.Lett. 88 (2002) 242301, 2002.
Inspire Record 568437 DOI 10.17182/hepdata.19421

Identified pi^[+/-] K^[+/-], p and p-bar transverse momentum spectra at mid-rapidity in sqrt(s_NN)=130 GeV Au-Au collisions were measured by the PHENIX experiment at RHIC as a function of collision centrality. Average transverse momenta increase with the number of participating nucleons in a similar way for all particle species. The multiplicity densities scale faster than the number of participating nucleons. Kaon and nucleon yields per participant increase faster than the pion yields. In central collisions at high transverse momenta (p_T greater than 2 GeV/c), anti-proton and proton yields are comparable to the pion yields.

Ratios of charged anti-particles to particles near mid-rapidity in Au + Au collisions at s(NN)**(1/2) = 130-GeV

The PHOBOS collaboration Back, B.B. ; Baker, M.D. ; Barton, D.S. ; et al.
Phys.Rev.Lett. 87 (2001) 102301, 2001.
Inspire Record 555572 DOI 10.17182/hepdata.41707

We have measured the ratios of antiparticles to particles for charged pions, kaons and protons near mid-rapidity in central Au+Au collisions at sqrt(s_NN) = 130 GeV. For protons, we observe pbar/p = 0.60 +/- 0.04 (stat.) +/- 0.06 (syst.) in the transverse momentum range 0.15 < p_T < 1.0 GeV/c. This leads to an estimate of the baryo-chemical potential mu_B of 45 MeV, a factor of 5-6 smaller than in central Pb+Pb collisions at sqrt(s_NN) = 17.2 GeV.
