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...

High 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...
