Anisotropy 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...
متن کاملClassical initial conditions in high energy nucleus-nucleus collisions
An iterative proceedure is proposed to compute the classical gauge field produced in the collision of two heavy nuclei at high energy. The leading order is obtained by linearizing the Yang-Mills equations in the light-cone gauge, and provides a simple formula for gluon production in nucleusnucleus collisions. At this order kt−factorization breaks down.
متن کاملHigh energy factorization in nucleus-nucleus collisions II - Multigluon correlations
We extend previous results (arXiv: 0804.2630 [hep-ph]) on factorization in high-energy nucleus-nucleus collisions by computing the inclusive multigluon spectrum to next-to-leading order. The factorization formula is strictly valid for multigluon emission in a slice of rapidity of width ∆Y ≤ α s . Our results shows that often neglected disconnected graphs dominate the inclusive multigluon spectr...
متن کاملDrell - Yan and J / ψ production in high energy proton - nucleus and nucleus - nucleus collisions ∗
The distributions of outgoing protons and charged hadrons in high energy protonnucleus collisions are described rather well by a linear extrapolation from proton-proton collisions. This linear extrapolation is applied to precisely measured Drell-Yan cross sections for 800 GeV protons incident on a variety of nuclear targets. The deviation from linear scaling in the atomic number A can be accoun...
