Charged hadrons (0.15 < p ⊥ < 4 GeV/ c ) associated with a large p ⊥ trigger particle (4 < p trig ⊥ < 6 GeV/ c ) are statistically reconstructed in the large acceptance STAR TPC for p+p and Au+Au collisions at GeV. Preliminary results on transverse momentum distributions of these hadrons are presented, separately on the near and the away side from the trigger particle. An increase in the multiplicity and total scalar p ⊥ of these hadrons from p+p to central Au+Au collisions is observed. The away-side distribution is found to be significantly softened in central Au+Au with respect to p+p collisions. The results are consistent with modification of jets in heavy-ion collisions at RHIC.
