Energy 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 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 کاملStrange Particle Production in Heavy Ion Collisions
Strangeness production in heavy ion collisions at relativistic energies provides one of the key information about the reaction mechanism and could indicate the onset of new phenomena. The attempts to describe the measured particle ratios including strange hadrons at AGS and SPS and recently also at RHIC using a strangeness fugacity are very successful [1]. However, the usual grand-canonical tre...
متن کاملA Study of Strange Particle Production In
A study of strange particle production in charged current interactions has been performed using the data from the NOMAD experiment. Yields of neutral strange particles (K 0 s , ,) have been measured. Mean multiplicities are reported as a function of the event kinematic variables E , W 2 and Q 2 as well as of the variables describing particle behaviour within a hadronic jet: x F , z and p 2 T. D...
متن کاملStrange Particle Production and s - quark Asymmetry
Using hadronic 2° decays recorded by the SLD experiment at SLAC, we have studied the production of strange particles as a function of momentum. A high-purity sample of K ~ was tagged using Cherenkov Ring Imaging Detector(CRID). The #, A and K. were reconstructed in the K+ K-, pm and ~+ T – modes respectively, and CRID identification of K+ and p was used to obtain pure samples of@ and A. We have...
