چکیده
We report new STAR measurements of midrapidity yields for the Λ, Λ[over ¯], K(S)(0), Ξ(-), Ξ[over ¯](+), Ω(-), Ω[over ¯](+) particles in Cu+Cu collisions at √S(NN)==200 GeV, and midrapidity yields for the Λ, Λ[over ¯], K(S)(0) particles in Au+Au at √S(NN)==200 GeV. We show that, at a given number of participating nucleons, the production of strange hadrons is higher in Cu+Cu collisions than in Au+Au collisions at the same center-of-mass energy. We find that aspects of the enhancement factors for all particles can be described by a parametrization based on the fraction of participants that undergo multiple collisions.

Antiparticle to particle ratios and identified hadron spectra in Cu+Cu and Au+Au collisions
New results on antiparticle to particle ratios in Cu+Cu and Au+Au collisions at √ s NN = 62.4 and 200 GeV from the PHOBOS experiment at RHIC are presented. Transverse momentum spectra of pions, kaons, protons and antiprotons from Au+Au collisions at √ s NN = 62.4 GeV close to mid-rapidity are also discussed. Antiparticle to particle ratios are found to be remarkably independent of the collision...
متن کاملParticle Production at RHIC
Identified hadron spectra and ratios provide a unique tool to study the bulk particle production in heavy-ion collisions and explore the QCD phase diagram. In these proceedings we present the analysis of charged pion, kaon and (anti)proton distributions from √ s NN = 200 and 62.4 GeV Cu+Cu collisions, collected by the STAR experiment. New measurements extend the systematic studies of bulk prope...

متن کاملSystematic Study of Identified Particle Production in PHENIX
Large enhancement of (anti)protons relative to pions has been observed at intermediate p T ∼ 2-5 GeV/c in central Au+Au collisions at RHIC. To investigate the possible source of this baryon enhancement, we performed a systematic study of identified hadron spectra in Au+Au and Cu+Cu collisions at √ s N N = 200 GeV, and Au+Au collisions at √ s N N = 62.4 GeV. The data set allows us to study the e...

The PHOBOS collaboration has measured transverse momentum distributions of charged hadrons produced in Cu+Cu collisions at √ s NN = 200 and 62.4 GeV. The nuclear modification factor R N part AA is calculated relative to p+p data at both collision energies as a function of collision centrality. For the same number of participating nucleons, R N part AA is essentially the same in both systems ove...
متن کامل8 Energy and system size dependence of φ meson production in Cu + Cu and Au + Au collisions
We study the beam-energy and system-size dependence of φ meson production (using the hadronic decay mode φ → K+K−) by comparing the new results from Cu+Cu collisions and previously reported Au+Au collisions at √ sNN = 62.4 and 200 GeV measured in the STAR experiment at RHIC. Data presented are from midrapidity (|y| <0.5) for 0.4 < pT < 5 GeV/c. At a given beam energy, the transverse momentum di...
