A 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 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 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 of Strange Particle Yields from a Qgp-fireball
We explore, as function of the collision energy and stopping in relativistic nuclear collisions, the production yields of strange particles, in particular strange antibaryons, assuming formation of a deconfined thermal QGP-fireball which undergoes a sudden hadronisation. The non-equilibrium freeze-out conditions are established and strange antibaryon excitation functions are shown to have chara...
