Measurement of nuclear-modification factors for π~0, η, and {symbol} mesons and protons in heavy-ion interactions in the PHENIX experiment

摘要

Light hadrons provide a convenient tool for studying the properties of hot and dense media formed in central collisions of relativistic heavy nuclei. The results obtained in the PHENIX experiment at the relativistic heavy-ion collider (RHIC, Brookhaven National Laboratory, USA) by measuring nuclearmodification factors for light hadrons in various colliding systems (pp, dAu, CuCu, and AuAu) at the c. m. energies of √s_(NN) = 62.4 and 200 GeV are presented.
