The perturbative QCD factorization approach in high energy nuclear collisions
I discuss the systematic modifications to the perturbative QCD factorization approach in high energy l+A, p+A and A+A reactions. These include transverse momentum diffusion manifest in the Cronin effect and a small increase in the dijet acoplanarity; nuclear size enhanced power corrections that lead to shadowing in deeply inelastic scattering and suppression of single and double inclusive hadro...
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 کاملHigh energy pA collisions in the Color Glass Condensate approach
We present a brief review of phenomenological applications of the gluon saturation approach to the proton-nucleus collisions at high energies.
متن کاملQuark pair production in high energy pA collisions: General features
A consistent treatment of both multiple scattering and small x quantum evolution effects on pair production in high energy pA collisions is feasible in the framework of the Color Glass Condensate (CGC) [1]. We first discuss the properties of quark pair production in the classical effective theory where only multiple scattering effects are included. Explicit results are given for pair production...
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...
