“…Several PHENIX studies (e.g., [39]) were restricted to 1D azimuth correlations. Other STAR and PHOBOS analyses have imposed so-called trigger-associated p t cuts (e.g., [40]), which retain only part of the jet structure and reduce or exclude other contributions.…”

We present two-dimensional (2D) two-particle angular correlations measured with the STAR detector on relative pseudorapidity η and azimuth φ for charged particles from Au-Au collisions at √ s NN = 62 and 200 GeV with transverse momentum p t 0.15 GeV/c, |η| 1, and 2π in azimuth. Observed correlations include a same-side (relative azimuth <π/2) 2D peak, a closely related away-side azimuth dipole, and an azimuth quadrupole conventionally associated with elliptic flow. The same-side 2D peak and away-side dipole are explained by semihard parton scattering and fragmentation (minijets) in proton-proton and peripheral nucleus-nucleus collisions. Those structures follow N -N binary-collision scaling in Au-Au collisions until midcentrality, where a transition to a qualitatively different centrality trend occurs within one 10% centrality bin. Above the transition point the number of same-side and away-side correlated pairs increases rapidly relative to binary-collision scaling, the η width of the same-side 2D peak also increases rapidly (η elongation), and the φ width actually decreases significantly. Those centrality trends are in marked contrast with conventional expectations for jet quenching in a dense medium. The observed centrality trends are compared to perturbative QCD predictions computed in HIJING, which serve as a theoretical baseline, and to the expected trends for semihard parton scattering and fragmentation in a thermalized opaque medium predicted by theoretical calculations and 064902-2 ANOMALOUS CENTRALITY EVOLUTION OF TWO-. . .PHYSICAL REVIEW C 86, 064902 (2012) phenomenological models. We are unable to reconcile a semihard parton scattering and fragmentation origin for the observed correlation structure and centrality trends with heavy-ion collision scenarios that invoke rapid parton thermalization. If the collision system turns out to be effectively opaque to few-GeV partons the present observations would be inconsistent with the minijet picture discussed here.

“…One possibility is in-medium parton energy loss followed by in-vacuum fragmentation, which naturally explains the observed high-p T inclusive hadron suppression, R AA , defined as a ratio of spectra measured in Au + Au collisions with respect to binary-scaled pp reference [13,14]. Such a scenario can also explain little to no modifications of near-side peaks in the two-particle correlations (I AA ) [11,12]; however, lack of broadening on the away side of such correlation functions poses a challenge for this model [12]. Alternatively, there could be a finite probability for both partons to escape the medium without interactions.…”

“…Thus, the partons and subsequently formed jets on the near and away sides can be affected by different underlying physics. However, di-hadron correlations between two high-p T particles exhibit jetlike peaks in both near and away sides [11,12] with little shape modification from d + Au to central Au + Au, but a strong suppression on the away-side amplitude. This observation may be interpreted in two jet-medium interaction scenarios.…”

Experimental studies of di-jets in Au+Au collisions using angular correlations with respect to back-to-back leading hadrons

et al. 2013

Jet-medium interactions are studied via a multihadron correlation technique (called "2 + 1"), where a pair of back-to-back hadron triggers with large transverse momentum is used as a proxy for a di-jet. This work extends the previous analysis for nearly symmetric trigger pairs with the highest momentum threshold of trigger hadron of 5 GeV/c with the new calorimeter-based triggers with energy thresholds of up to 10 GeV and above. The distributions of associated hadrons are studied in terms of correlation shapes and per-trigger yields on each trigger side. In contrast with di-hadron correlation results with single triggers, the associated hadron distributions for back-to-back triggers from central Au + Au data at (2013) to the near-side and away-side of jetlike peaks is observed. The relative imbalance in the Au + Au measurement with respect to d + Au reference is found to increase with the asymmetry of the trigger pair, consistent with the expectation from medium-induced energy-loss effects. In addition, this relative total transverse momentum imbalance is found to decrease for softer associated hadrons. Such evolution indicates that the energy missing at higher associated momenta is converted into softer hadrons.

With a view to understanding J/Ψ suppression in relativistic heavy ion collisions, we compute the suppression rate within the framework of hydrodynamical evolution model. For this, we consider an ellipsoidal flow and use an ansatz for temperature profile function which accounts for time and the three dimensional space evolution of the quark-gluon plasma. We have calculated the survival probability separately as the function of transverse and longitudinal momentum. We have shown that previous calculations are special cases of this model. KeywordsRelativistic heavy ion collisions, quark-gluon plasma, momentum dependence, suppression rate.
