Аннотация
High transverse momentum (p(T)) particle production is suppressed owing to the parton (jet) energy loss in the hot dense medium created in relativistic heavy-ion collisions. Redistribution of energy at low-to-modest p(T) has been difficult to measure, owing to large anisotropic backgrounds. We report a data-driven method for background evaluation and subtraction, exploiting the away-side pseudorapidity gaps, to measure the jetlike correlation shape in Au+Au collisions at root S-NN = 200 GeV in the STAR experiment. The correlation shapes, for trigger particles p(T) > 3 GeV/c and various associated particle p(T) ranges within 0.5 < p(T) < 10Gev/c, are consistent with Gaussians, and their widths increase with centrality. The results indicate jet broadening in the medium created in central heavy-ion collisions.
