Strangeness enhancement in Cu-Cu and Au-Au collisions at √S(NN)=200 GeV.
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 i...

متن کاملRAPIDITY IN √ s NN = 200 GeV Au + Au COLLISIONS Eric
Title of dissertation: ELLIPTIC FLOW AT FORWARD RAPIDITY IN √ sNN = 200 GeV Au+Au COLLISIONS Eric Michael Richardson, Doctor of Philosophy, 2012 Dissertation directed by: Professor Alice C. Mignerey Department of Chemistry and Biochemistry Forward rapidity elliptic flow (v2) of both unidentified charged hadrons and decay muons has been measured from √ sNN = 200 GeV Au+Au collisions as a functio...
متن کاملAnisotropic flow in Cu + Au collisions at √ sN N = 200 GeV
The anisotropic flow of charged hadrons in asymmetric Cu+Au collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Compared with previous results for symmetric Au+Au collisions, charged hadrons produced around midrapidity in asymmetric collisions are found to have a stronger directed flow v1 and their elliptic flow v2 is also more sensitive to the parton s...
متن کاملAntiparticle 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...
