Beam Energy Dependence of Jet-Quenching Effects in Au plus Au Collisions at root s(NN)=7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV
We report measurements of the nuclear modification factor R-CP for charged hadrons as well as identified pi (+(-)) K+(-), and p((p) over bar) for Au + Au collision energies of root s(NN) = 7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV. We observe a clear hi
