What is recorded here?
PHENIX measured high-transverse-momentum charged hadrons in gold–gold collisions at 200 GeV per nucleon pair and compared them with neutral-pion and nucleon-collision references. Central gold–gold collisions showed strong suppression, whereas the deuteron–gold control showed no comparable suppression and a modest charged-hadron enhancement. Together the measurements support a dense-medium final-state interpretation.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The comparison is restricted to the cited collision energies, centrality selections, midrapidity acceptance and measured momentum ranges. The charged-hadron proton–proton reference was constructed using the neutral-pion spectrum and a hadron-to-pion ratio, and binary-collision normalization uses a Glauber model. Suppression is an observation; parton energy loss and the microscopic state of the medium are interpretations, not a direct unique identification from these measurements alone.
