Strange Particle Production in p+p, p+Pb and Pb+Pb Interactions from NA49
Recent NA49 results on Λ, ¯ Λ, Ξ − and ¯ Ξ + production in minimum bias p+p and centrality selected p+Pb collisions at 158 GeV/c, and the results on Λ, ¯ Λ, K + and K − production in central Pb+Pb collisions at 40, 80 and 158 A·GeV are discussed and compared with other available data. By comparing the energy dependence of Λ and ¯ Λ production at mid-rapidity a striking similarity is observed be...
متن کاملStrange Particle Production in Nuclear Collisions at Cern-na49
D. BARNA for the NA49 Collaboration Central Research Institute for Physics, Konkoly-Thege út 29-33, H-1121, Budapest, Hungary In order to quantify isospin effects in the comparison of elementary to nuclear collisions, p-p and n-p interactions have been studied in the NA49 experiment in addition to p-Pb and PbPb reactions. Together with first measurements of cascade hyperon and Ω production in p...
متن کاملStrange and Multi-Strange Particle Production in ALICE
The production of strange and multi-strange hadrons in proton-proton (pp) and lead-lead (Pb-Pb) collisions is studied with the ALICE experiment at the CERN LHC. These particles are reconstructed via their weak decay topologies, exploiting the tracking and particle identification capabilities of ALICE. Measurements of central rapidity yields of Λ, Ξ− and Ω− baryons, their antiparticles and KS me...
متن کاملEnergy Dependence Systematics of Strange and Multi-strange Particle Production
We present results on systematic measurements of strange and multi-strange particles with the STAR detector for center of mass energies per nucleon pair ( √ sNN ) of 62.4 and 200 GeV in ultra-relativistic Au+Au collisions at RHIC. We use these results to characterize the chemical and kinetic freeze-out properties of the fireball produced by the collision. This is done by comparison to statistic...
متن کاملStrange Particle Production and Elliptic Flow from CERES
Elliptic flow measurements as a function of pT of charged (π ± and low-pT protons) and strange (Λ and K S) particles from Pb+Au collisions at 158 AGeV/c are presented, together with measurements of φ and K S meson production. A mass ordering effect was observed. Scaling to the number of constituent quarks and transverse rapidity y T scaling are presented. The results are compared with results f...
