Long Range Correlations in P–Pb Collisions at $\sqrt{s_\mathrm{{NN}}}$ = 5.02 TeV with ALICE

Angular correlation measurements between charged particles revealed the existence of a double-ridge in p–Pb collisions. Similar correlations between particles separated by several units of pseudorapidity in Pb–Pb collisions were attributed to collectivity in heavy ion collisions. We present the correlations between forward trigger muons and mid-rapidity associated hadrons measured in p–Pb collisions which show that the double-ridge extends up to $|\varDelta \eta |$ <5.0 and the $v_{2}$ of muons is (16 ± 6%) higher in Pb-going than in p-going directions.
