Energy dependence of strangeness production
We present a summary of strange particle yields measured by the experiment NA49 in central Pb+Pb collisions in the beam energy range 20 158 AGeV. The comparison with thermal hadron model results shows that above 30 AGeV, a strangeness undersaturation parameter γS must be employed to describe the data. This suggests a change in the strangeness production mechanism at this energy. We find that th...
متن کاملSystem and Energy Dependence of Strangeness Production with STAR
The yields and spectra of strange hadrons have each been measured by STAR as a function of centrality in √ sNN = 200 GeV AuAu collisions. By comparing to pp and dAu at √ sNN = 200 GeV and in AuAu at √ sNN = 62 GeV the dependence on system size and energy is studied. Strange resonances, such as Σ(1385) and Λ(1520), are used to examine the dynamical evolution between production and freeze-out for...
متن کاملSystem-size dependence of strangeness production in high-energy A+A collisions and percolation of strings
The CERN-NA49 Collaboration has recently published the yields of a series of strangeness-carrying particles (charged kaons,Λ, φ, in addition charged pions for normalization) in central C+C and Si+Si collisions at the top SPS energy ( √ sNN = 17.3 GeV) [1]. Together with earlier data for p+p, S+S and Pb+Pb the systematics of strangeness production as a function of the size of the collision syste...
متن کاملEnergy and System Size Dependence of Strangeness Production from SPS to RHIC
Strange particle production is an important experimental observable that allows the study of the strongly interacting matter created in relativistic heavy-ion collisions. The STAR experiment at RHIC has a unique capability of measuring identified strange particles over a wide range of acceptance providing a rich set of data to perform a systematic study. In addition to the data from Au+Au colli...
متن کاملStrangeness Saturation: Dependence on System-Size, Centrality and Energy
The dependence of the strangeness saturation factor on the system size, centrality and energy is studied in relativistic heavy-ion collisions.
