We discuss a simple generic model of ``jet quenching'' in which matter absorption is defined by one parameter. We show that as absorption grows, the azimuthal asymmetry parameter ${v}_{2}$ grows as well, reaching the finite limit ${v}_{2}^{*}$ which has a simple geometric interpretation. We show that this limit is still below the experimental values for $6g{p}_{t}g2 \mathrm{GeV},$ according to preliminary data from the STAR experiment at RHIC. We thus conclude that jet quenching models alone…

Role of QCD monopoles in jet quenching

QCD monopoles are magnetically charged quasiparticles whose Bose-Einstein condensation (BEC) at $T T_c$ is responsible for the unusual kinetic properties of QGP. In this paper, we study the

How ‘strange’ is high-p⊥ physics at RHIC?

A review of experimental results obtained during the first two RHIC runs is presented. The discoveries of suppression of high-p⊥ (p⊥ ≥ 2 GeV/c) hadrons and the vanishing back-to-back angular

Measurements of azimuthal anisotropies of jet production in Pb+Pb collisions at $\sqrt{s_{NN}} =$ 5.02 TeV with the ATLAS detector

The azimuthal variation of jet yields in heavy-ion collisions provides information about the path-length dependence of the energy loss experienced by partons passing through the hot, dense nuclear

Large observed v(2) as a signature for deconfinement

We present a new plot for representing R AA(o) data that emphasizes the strong correlation between high-p η suppression and its elliptic anisotropy. We demonstrate that existing models cannot

Pseudorapidity dependence of parton energy loss in relativistic heavy ion collisions

We analyze the recent data from the BRAHMS Collaboration on the pseudorapidity dependence of nuclear modification factors in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV by using the full three

Detailed study of high-p(T) neutral pion suppression and azimuthal anisotropy in Au plus Au collisions at root s(NN) =200 GeV

Measurements of neutral pion (pi(0)) production at midrapidity in root s(NN)=200 GeV Au+Au collisions as a function of transverse momentum, p(T), collision centrality, and angle with respect to

High-pT π0 production with respect to the reaction plane using the PHENIX detector at RHIC

The origin of the azimuthal anisotropy in particle yields at high pT (pT>5 GeV/c) in RHIC collisions remains an intriguing puzzle. Traditional flow and parton energy loss models have failed to

Measurement of Prompt D^{0} Meson Azimuthal Anisotropy in Pb-Pb Collisions at sqrt[s_{NN}]=5.02  TeV.

The results are consistent with the presence of collective motion of Charm quarks at low p_{T} and a path length dependence of charm quark energy loss at high p_{ t}, thereby providing new constraints on the theoretical description of the interactions between charm quarks and the quark-gluon plasma.
