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 کاملAsymptotic properties of high-pT particle production in hadron-hadron, hadron-nucleus and nucleus-nucleus collisions at high energies
The concept of z-scaling reflecting the general features of internal particle substructure, constituent interaction and mechanism of real particle formation is reviewed. Experimental data on the cross sections obtained at ISR, SpS and Tevatron are used in the analysis. The properties of data z-presentation, the energy and angular independencies, the power law, Aand F -dependencies, are discusse...
متن کاملProton–Nucleus Cross Section at High Energies
Cross sections for proton inelastic collision with different nuclei are described within the Glauber and multiple scattering approximations. A significant difference between approximate “Glauber” formula and exact calculations with a geometrical scaling assumption for very high-energy cross section is shown. Experimental values of proton–proton cross sections obtained using extensive air shower...
متن کاملAnisotropy in High Energy Nucleus - Nucleus Collisions
The predictions of event anisotropy parameters from transport model RQMD are compared with the recent experimental measurements for 158A GeV Pb+Pb collisions. Using the same model, we study the time evolution of event anisotropy at 2A GeV and 158A GeV for several colliding systems. For the first time, both momentum and configuration space information are studied using the Fourier analysis of th...
متن کاملHigh energy factorization in nucleus-nucleus collisions
We derive a high energy factorization theorem for inclusive gluon production in A+A collisions. Our factorized formula resums i) all order leading logarithms (g ln(1/x1,2)) n of the incoming partons momentum fractions, and ii) all contributions (gρ1,2) n that are enhanced when the color charge densities in the two nuclei are of order of the inverse coupling– ρ1,2 ∼ g . The resummed inclusive gl...
