Azimuthal angular correlations in two-particle production in proton-nucleus collisions
Presented by Jamal JALILIAN-MARIAN on 15 Aug 2012 from 09:10 to 09:30
Type: Oral Presentation
Di-hadron azimuthal angular correlations in the forward rapidity region of deuteron-nucleus collisions at RHIC show a disappearance of the away side peak with centrality and transverse momentum. This can be understood, in the Color Glass Condensate (CGC) formalism, to be due to multi-gluon exchanges between the projectile and target. We show that CGC formalism predicts a similar disappearance of the away side peak in the prompt photon-hadron azimuthal angular correlations. We make detailed predictions for transverse momentum and centrality dependence of this disappearance in deuteron-gold collisions at RHIC and proton-nucleus collisions at the LHC.
