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...
متن کاملThe 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 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 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...
متن کاملHigh energy factorization in nucleus-nucleus collisions III. Long range rapidity correlations
We obtain a novel result in QCD for long range rapidity correlations between gluons produced in the collision of saturated high energy hadrons or nuclei. This result, obtained in a high energy factorization framework, provides strong justification for the Glasma flux tube picture of coherent strong color fields. Our formalism can be applied to “near side ridge” events at RHIC and in future stud...
