Abstract
We present preliminary STAR results on three-particle azimuthal angle correlation studies in Au+Au collisions at GeV. The studies are carried out at mid-rapidity between a trigger particle with 3 ⩽p⊥⩽ 4 GeV/c and two associated particles in 1 ⩽p⊥⩽ 2 GeV/c. A cumulant analysis reveals finite three-particle azimuthal correlations, dominated by near- and away-side particle correlations consistent with jet production, and jet-flow correlations. We use a two-component model to remove underlying background correlations. This analysis indicates the presence of the conical emission signals in central Au+Au collisions within the model assumptions about background composition and normalization.
