Transverse momentum spectra for charged hadrons and for neutral pions in the range 1 Gev/c < P-T < 5 GeV/c have been measured by the PHENIX experiment at RHIC in Au + Au collisions at rootS(NN) = 130 GeV. At high p(T) the spectra from peripheral nuclear collisions are consistent with scaling the spectra from p + p collisions by the average number of binary nucleon-nucleon collisions. The spectra from central collisions are significantly suppressed when compared to the binary-scaled p + p expectation, and also when compared to similarly binary-scaled peripheral collisions, indicating a novel nuclear-medium effect in central nuclear collisions at RHIC energies.

Strongly correlated quantum fluids: ultracold quantum gases, quantum chromodynamic plasmas and holographic duality (2012, background): “This idea was proposed as far back as 1982 by Bjorken, placed on firmer theoretical footing in the early 1990’s, and finally discovered experimentally by RHIC experiments in the early part of the 2000’s [268].”
Measurement of jet suppression in central Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV (2015, background): “Jet quenching has been observed at RHIC [20–29] and at the LHC [8, 16, 17, 30–41] via the measurement of inclusive hadron and jet production at high p T , di-hadron angular correlations and the dijet energy imbalance.”
Mapping the phases of quantum chromodynamics with beam energy scan (2019, background): “The central discoveries at RHIC, and later confirmed and refined at the LHC, include a large azimuthal asymmetry, known as elliptic flow v2, in the particle yields [22], as well as a strong suppression of high energy jets and heavy quarks [23].”

A hybrid strong/weak coupling approach to jet quenching (2014, background): “The phenomenon of jet quenching was discovered prior to the LHC measurements, without reconstructing individual jets, primarily via the strong reduction in the number of intermediate-pT hadrons in heavy ion collisions at RHIC relative to protonproton collisions [3, 4].”
