High Energy Factorization in the Glasma and Long Range Rapidity Correlations in QCD
Raju Venugopalan (BNL)

Abstract: 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 ``sphaleron-like" color fields that are produced at early times after a heavy ion collision. Our formalism can be applied to ``near side ridge" events at RHIC and in future studies of long range rapidity correlations at the LHC.
