ANGULAR AND LONG RANGE RAPIDITY CORRELATIONS IN PARTICLE PRODUCTION AT HIGH ENERGY

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...

Angular and momentum asymmetry in particle production at high energies

Angular asymmetry and momentum disbalance for a pair of particles produced at high energy in central rapidity region are studied. The asymmetry is substantial for small momenta of produced particles but diminishes when they rise.

Long-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...

Charged Particle Production at High Rapidity in p+p Collisions at RHIC

This report describes the recent analysis of identified charged particle production at high rapidity performed on data collected from p+p collisions at RHIC ( √ s = 200GeV). The extracted invariant cross-sections compare well to NLO pQCD calculations. However, a puzzling high yield of protons at high rapidity and pT has been found. INTRODUCTION The p+p system is used in many cases as a paradigm...
