Nucleus - nucleus collisions at high baryon densities
We study central collision of P b + P b at 20, 40, 80 and 160 A·GeV within the UrQMD transport approach and compare rapidity distributions of π − , K + , K − and Λ with the recent measurements from the NA49 Collaboration at 40, 80 and 160 A·GeV. It is found that the UrQMD model reasonably describes the data, however, systematically overpredicts the π − yield by ∼ 20%, whereas the K + yield is u...
متن کاملBaryon - to - Entropy Ratio in Very High Energy Nuclear Collisions
We compute as a function of rapidity y the baryon number carried by quarks and antiquarks with pT > p0 ≈ 2 GeV produced in Pb+Pb collisions at TeV energies. The computation is carried out in lowest order QCD perturbation theory using structure functions compatible with HERA results. At p0 = 2 GeV the initial gluon density is both transversally saturated and thermalised in the sense that the ene...
متن کاملBaryon Number Transport in High Energy Nuclear Collisions
Abstract: Recent SPS data on the rapidity distribution of protons in p+S, p+Au and S+S collisions at 200 AGeV and preliminary Pb+Pb collisions at 160 AGeV are compared to HIJING and VENUS calculations as well as to predictions based on the Multi-Chain Model (MCM). The preliminary Pb data suggest that a linear dependence of the proton rapidity shift as a function of the nuclear thickness, as fir...
متن کاملQuantifying Baryon Stopping in High Energy Nuclear Collisions
We propose a numerical definition for baryon stopping in relativistic heavy ion collisions that is obtainable from final hadron rapidity distributions as well as from bremsstrahlung measurements. Thus a new channel of communication is opened between the two methods. PACS: 25.75.-q, 13.40.-f
متن کاملHigh Energy Nuclear Collisions
Highlights of the results from ultrarelativistic heavy ion collisions at CERN-SPS are reviewed. In particular, I discuss how the experimental results indicate that a collective strongly interacting system has been produced, and what are the implications towards the Quark Gluon Plasma. The physical ideas behind measuring certain observables are introduced. The future program of high energy nucle...
