Jet-like correlations with direct-photon and neutral-pion triggers at root S-NN=200 GeV
Original language description
Azimuthal correlations of charged hadrons with direct-photon (gamma(dir)) and neutral-pion (pi(0)) trigger particles are analyzed in central Au+Au and minimum-bias p + p collisions at root S-NN = 200 GeV in the STAR experiment. The charged-hadron per-trigger yields at mid-rapidity from central Au+Au collisions are compared with p + p collisions to quantify the suppression in Au+Au collisions. The suppression of the away-side associated-particle yields per gamma(dir) trigger is independent of the transverse momentum of the trigger particle (p(T)(trig)), whereas the suppression is smaller at low transverse momentum of the associated charged hadrons (p(T)(assoc)). Within uncertainty, similar levels of suppression are observed for gamma(dir) and pi(0) triggers as a function of z(T) (equivalent to p(T)(assoc)/p(T)(tri)). The results are compared with energy-loss-inspired theoretical model predictions. Our studies support previous conclusions that the lost energy reappears predominantly at low transverse momentum, regardless of the trigger energy.
