FYI another on-slaught of STAR papers presenting results that in fact has been shown extensively.

The titles and asbtracts | for these papers are enclosed below. | | Sincerely, | | Tim | | | | STAR PRL Submission on Rho_zero Production: | | "Rho0 Production and Possible Modification in Au+Au and | p+p Collisions at sqrt(s_NN) = 200 GeV | | Abstract: | We report results on rho(770)0 -> pi+ + pi- production at | mid-rapidity in p+p and peripheral Au+Au collisions at | sqrt(s_NN) = 200 GeV. This is the first direct measurement | of rho(770)0 -> pi+ + pi- in heavy-ion collisions. The rho0 | mass is significantly shifted in minimum bias p+p and peripheral | Au+Au interactions. The rho0 mass shift is dependent on | transverse momentum and multiplicity. The modification of the | rho0 meson mass, width, and shape due to phase space and | dynamical effects are discussed. | | | STAR PRL Submission on pi-K Correlations: | | Pion-Kaon correlations in Au+Au collisions at | $\sqrt{s_{NN}} = 130$ GeV | | Abstract: | | Pion-kaon correlation functions are constructed from | central Au+Au data taken at $\sqrt{s_{NN}} = 130$ GeV. | The results suggest that pions and kaons are not emitted | at the same average space-time point. Space-momentum | correlations, i.e. transverse flow, lead to a space-time emission | asymmetry of pions and kaons that is consistent with the | data. This result provides new independent evidence that | the system created at RHIC undergoes a collective transverse | expansion. | | | STAR PRL Submission on Multi-Strange Baryons: | | "Multi-Strange Baryon Production in Au-Au Collisions | at roots_NN = 130 GeV" | | The transverse mass spectra and mid-rapidity yields for cascades | and omegas plus their anti-particles are presented. The 10% most | central collision yields suggest that the amount of multi-strange | particles produced per charged hadron increases from SPS to | RHIC energies. A hydrodynamically inspired model fit to the | spectra, which assumes a thermalized source, seems to indicate | that these multi-strange particles experience a significant transverse | flow effect but are emitted when the system is hotter and the flow | is smaller than values obtained from a combined fit to pions, | kaons, protons, and lambdas. | | |
