High 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...
متن کاملLong-range rapidity correlations in heavy ion collisions at strong coupling from AdS/CFT
We use AdS/CFT correspondence to study two-particle correlations in heavy ion collisions at strong coupling. Modeling the colliding heavy ions by shock waves on the gravity side, we observe that at early times after the collision there are long-range rapidity correlations present in the two-point functions for the glueball and the energymomentum tensor operators. We estimate rapidity correlatio...
متن کاملTwo particle rapidity, transverse momentum, and azimuthal correlations in relativistic nuclear collisions and transverse radial expansion
At the very first stage of an ultra-relativistic nucleus-nucleus collision new particles are produced in individual nucleon-nucleon collisions. In the transverse plane, all particles from a single NN collision are initially located at the same position. The subsequent transverse radial expansion of the system creates strong position-momentum correlations and leads to characteristic rapidity, tr...
متن کاملRapidity and centrality dependence of azimuthal correlations in high energy d+Au collisions
We discuss azimuthal correlations in dAu collisions at different rapidities and centralities and argue that experimentally observed depletion of the back-to-back bump can be quantitatively explained by gluon saturation in the Color Glass Condensate of the Gold nucleus.
متن کاملThree-particle coincidence of the long range pseudorapidity correlation in high energy nucleus-nucleus collisions.
We report the first three-particle coincidence measurement in pseudorapidity (Δη) between a high transverse momentum (p⊥) trigger particle and two lower p⊥ associated particles within azimuth |Δϕ|<0.7 in square root of s(NN)=200 GeV d+Au and Au+Au collisions. Charge ordering properties are exploited to separate the jetlike component and the ridge (long range Δη correlation). The results indicat...
