“…It has also been argued recently that this long-range correlation in η could be caused by long-range structures in the medium, due to density fluctuations in the medium [29] or color flux tubes [30][31][32]. The "ridge"-like correlation structure in η is further explored in other STAR publications [26,[33][34][35].…”

a large enhancement of the near-( φ ∼ 0) and away-side ( φ ∼ π ) associated yields is found, together with a strong broadening of the away-side azimuthal distributions in Au + Au collisions compared to d + Au measurements, suggesting that other particle production mechanisms play a role. This is further supported by the observed significant softening of the away-side associated particle yield distribution at φ ∼ π in central Au + Au collisions.

“…In p+p and d+Au collisions, there is a peak narrow in azimuth ( φ) and pseudorapidity ( η) around the trigger particle, which we refer to as the jet-like correlation. This peak is also present in Au+Au collisons, but an additional structure which is narrow in azimuth but broad in pseudorapidity has been observed in central Au+Au collisions at √ s NN = 200 GeV [8,[12][13][14]. This structure, called the ridge, is independent of η within the Solenoidal Tracker at RHIC (STAR) acceptance, | η| < 2.0, within errors, and persists to high p T (p trigger T ≈ 6 GeV/c, p associated T ≈ 3 GeV/c).…”

“…The 5% systematic error due to the uncertainty on the associated particle's efficiency is not shown and systematic errors due to the acceptance correction are given in Table II. A recent STAR study of the ridge using two-particle azimuthal correlations with respect to the event plane [14] in Au+Au collisions at √ s NN = 200 GeV shows that the ridge yield is dependent on the angle of the trigger particle relative to the event plane. Another STAR study of three-particle correlations in pseudorapidity [13] Table II. precision, particles in the ridge are uncorrelated in η with both the trigger particle and each other. These observations along with the PHOBOS measurement of the ridge out to η = 4 [15] provide substantial experimental constraints on theories for the production of the ridge.…”

“…Jet quenching [1] was first observed as the suppression of inclusive hadron spectra at large transverse momenta (p T ) in central Au+Au collisions with respect to p+p data scaled by number of binary nucleon-nucleon collisions [2][3][4][5][6][7]. Properties of jets at RHIC have been studied extensively using dihadron correlations relative to a trigger particle with large transverse momentum [8][9][10][11][12][13][14]. Systematic studies of associated particle distributions on the opposite side of the trigger particle revealed their significant modification in Au+Au relative to p+p and d+Au collisions at the top RHIC energy of √ s NN = 200 GeV.…”

Two-particle azimuthal ( φ) and pseudorapidity ( η) correlations using a trigger particle with large transverse momentum (p T ) in d+Au, Cu+Cu, and Au+Au collisions at √ s NN = 62.4 GeV and 200 GeV from the STAR experiment at the Relativistic Heavy Ion Collider are presented. The near-side correlation is separated into a jet-like component, narrow in both φ and η, and the ridge, narrow in φ but broad in η. Both components are studied as a function of collision centrality, and the jet-like correlation is studied as a function of the trigger and associated p T . The behavior of the jet-like component is remarkably consistent for different collision systems, suggesting it is produced by fragmentation. The width of the jet-like correlation is found to increase with the system size. The ridge, previously observed in Au+Au collisions at √ s NN = 200 GeV, is also found in Cu+Cu collisions and in collisions at √ s NN = 62.4 GeV, but is found to be substantially smaller at √ s NN = 62.4 GeV than at √ s NN = 200 GeV for the same average number of participants ( N part ). Measurements of the ridge are compared to models.

“…2, the near-side correlations are mostly consistent with zero within systematic uncertainties. Previous dihadron correlations without v 3 subtraction have shown a near-side correlation at large η in heavy-ion collisions [5,31], called the ridge, suggesting the ridge appears to be mainly due to v 3 . However, there appears a finite ridge remaining for in-plane trigger particles (φ s < 15…”
