Gluon production in heavy light ion collisions

We study gluon production in the early stages of heavy ion collisions in the saturation Color Glass Condensate framework assuming for simplicity that one colliding nucleus is much larger than the other This allows us to take into account two nucleons in the projectile nucleus while considering all of the nucleons inside the target nucleus in what we refer to as the heavy light ion regime Using this regime we study two particle long range rapidity correlations by calculating two gluon correlations We find equal away and near side azimuthal correlations which are long range in rapidity Furthermore we find contributions which correspond to Hanbury Brown and Twiss HBT correlations and contributions which are due to the Bose enhancement of the projectile
