Azimuthal di-hadron correlations in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV from STAR

Abstract

We present the centrality dependence of the azimuthal angle correlation shapes between a trigger and associated charged hadrons in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV from the STAR experiment. The away-side structure is significantly modified in central collisions and is characterised in terms of a doubly-peaked yield. A minimum in the <$p_T$> of hadrons opposite to the trigger particle is also investigated.
