Angular correlations between forward-rapidity muons and mid-rapidity charged particles in p-Pb collisions at $\surd $s$_{\mathrm{NN}}=$ 5.02 TeV
ORAL
Abstract
Two particle angular correlations have been used as a powerful tool in exploring particle production mechanism in relativistic heavy ion physics. Angular correlations between forward-rapidity muons (-4.0 \textless\ $\eta _{\mathrm{lab}}$ \textless\ -2.5) and mid-rapidity charged particles (-0.9 \textless\ $\eta_{\mathrm{lab}}$ \textless\ 0.9) are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV in 2013. These unique kinematics allow us to access the small-x region of the Pb nucleus, where high gluon densities are expected. Muon-hadron correlations, expected to have features that exhibit gluon saturation, are compared to calculations using a Color Glass Condensate (CGC) model, as well as mid-rapidity di-hadron correlations by the ALICE collaboration. Previous forward-rapidity two particle correlations in d-Au collisions at RHIC will also be compared.
