Hadron Spectra at High Rapidity
We report the measurement of charged hadron production at different pseudo-rapidity values in deuteron+gold as well as proton-proton collisions at √ sNN = 200GeV at RHIC. The nuclear modification factors RdAu and Rcp are used to investigate new behaviors in the deuteron+gold system as function of rapidity and the centrality of the collisions respectively.
متن کاملAnomalous net-baryon-rapidity spectra at RHIC
Net-baryon rapidity distributions in central Au+Au collisions at √ sNN = 200 GeV are shown to consist of three components. The nonequilibrium contributions are accounted for in a Relativistic Diffusion Model. Near midrapidity, a third fraction containing Zeq ≃ 22 protons reaches local statistical equilibrium in a discontinuous transition. It may be associated with a deconfinement of the partici...

متن کاملAnomalous diffusion in non-equilibrium relativistic heavy-ion rapidity spectra
There is experimental and theoretical evidence that the broad rapidity distribution of net proton yield (p − p) in central heavy-ion collisions at SPS energies could be a signal of non-equilibrium properties of the system. We show that the broad rapidity shape can be well reproduced in the framework of a non-linear relativistic Fokker-Planck dynamics which incorporates non-extensive statistics ...
متن کاملRapidity-dependent spectra from a single-freeze-out model of relativistic heavy-ion collisions
An extension of the single-freeze-out model with thermal and geometric parameters dependent on the spatial rapidity, α‖, is used to describe the rapidity and transverse-momentum spectra of pions, kaons, protons, and antiprotons measured at RHIC at √ sNN = 200 GeV by the BRAHMS collaboration. THERMINATOR is used to perform the necessary simulation, which includes all resonance decays. The result...
