Abstract (data abstract)
BNL-RHIC. The paper includes measurements of the charged-particle jet yields at midrapidity by the STAR experiment in Au+Au collisions at 200 GeV. The jets were reconstructed with the anti-kT algorithm for resolution parameter R=0.2, 0.3, and 0.4 in central (0-10%) and peripheral (60-80%) centrality using a low cut on transverse momentum of jet constituents (pT>0.2 GeV/c). To suppress the large combinatorial background a cut on pT of a leading particle in jet is imposed. From the charged-particle jet yields nuclear modification factor R_AA and R_CP are calculated along with the spectra ratios at various R.
