Energy dependence of Λ and Ξ production in centralPb+Pbcollisions at20A,30A,40A,

Abstract: Results on ,¯ , − , and¯ + production in central Pb+Pb reactions at 20A, 30A, 40A, 80A, and 158A GeV are presented. The energy dependence of transverse mass spectra, rapidity spectra, and multiplicities is discussed. Comparisons to string hadronic models (UrQMD and HSD) and statistical hadron gas models are shown. Although the latter provide a reasonable description of all particle yields, the first class of models fails to match the − and¯ + multiplicities.

“…From this figure it is also seen that lighter mesons like π − and K − show a fair agreement between experimental data [9,[13][14][15][16][17][18][19][20][21][22][23] and UrQMD prediction at all energies. However, for heavier meson like φ, as the energy of collision increases, there is a considerable disagreement between the observed and UrQMD predicted values.…”

“…In Fig. 1, the rapidity distributions of a few hadrons such as π − , k − , φ, and produced in UrQMD generated Au + Au collisions at 10, 20, 30 and 40 A GeV are plotted and compared with the existing Super Proton Synchrotron (SPS) [9,[13][14][15][16] and Alternating Gradient Synchrotron (AGS) (E802, E877, E896, E917) [17][18][19][20][21][22][23] data at the same energies. It is seen from this figure that, with UrQMD generated events, the rapidity distribution of ( + 0 ) and not alone gives a better agreement with the experimental data on .…”

“…Strange quarks are expected to be abundant in a deconfined medium due to the short time needed to reach equilibrium values among the parton species and to the lower energy threshold for ss production. A pattern of strangeness enhancement increasing with the hadron strangeness content when going from pp (p-A) to heavy-ion collisions was observed at the SPS [31][32][33][34], at RHIC [35] and at the LHC [36]. In the frame of the statistical hadronisation models, strange particle production in heavy-ion collisions follows the expectation for a grand-canonical ensemble.…”

“…The (Color online) Energy dependence of the ratios K + /π + , /π + , and /p in the HRG model at midrapidity as compared to experimental data at AGS [37], SPS [38], RHIC [29,31], and LHC [34,35]. monotonous increase of antinuclei abundance with √ s NN clearly suggests that at RHIC and LHC energies reconstruction of more massive antinuclei may become feasible.…”
