چکیده

Suppression of jet spectra or quenching in high-energy heavy-ion collisions is caused by energy loss the dense medium. The azimuthal anisotropy noncentral can lead to finite values anisotropic flow coefficients. This investigated within linear Boltzmann transport model, which simulates both elastic scattering and medium-induced gluon radiation based on perturbative quantum chromodynamics for shower medium recoil partons as well radiated gluons they propagate through quark-gluon plasma. dynamical evolution plasma each event provided $(3+1)$-dimensional CLVisc hydrodynamic model with fully fluctuating initial conditions. framework has been shown describe suppression single inclusive spectra. We calculate this study elliptic $({v}_{2}^{\mathrm{jet}})$ triangular $({v}_{3}^{\mathrm{jet}})$ coefficients $\text{Pb}+\text{Pb}$ at Large Hadron Collider energies. investigate colliding energy, centrality, transverse momentum dependence anisotropy, their event-by-event correlation soft bulk hadrons. An approximate between ${v}_{2}$ found. effect ${v}_{n}$ fluctuation ${v}_{n}^{\mathrm{jet}}$ found negligible. also jet-induced excitation, influenced radial flow, ${v}_{2}^{\mathrm{jet}}$. sensitivity ${v}_{2}^{\mathrm{jet}}$ shear viscosity studied.

Jet Tomography of Quark Gluon Plasma

Recent experimental measurements of high pT hadron spectra and jet correlation at RHIC are analyzed within a parton model which incoporates initial jet production and final propagation in heavy-ion collisions. The suppresion of single hadron spectra, back-to-back correlation, their centrality dependence and azimuthal anisotropy point to a dense matter with an initial parton density about 30 tim...

Jet conversions in a quark-gluon plasma

Quark and gluon jets traversing through a quark-gluon plasma not only lose their energies but also can undergo flavor conversions. The conversion rates via the elastic q(q̄)g → gq(q̄) and the inelastic qq̄ ↔ gg scatterings are evaluated in the lowest order in QCD. Including both jet energy loss and conversions in the expanding quark-gluon plasma produced in relativistic heavy ion collisions, we ha...

Hard QCD Probes to Quark-Gluon Plasma

Completely unexplored regimes of QCD, dominated by high-density/temperature effects, are available in heavy ion experiments at collider energies. The successful RHIC program shows how relevant the high transverse momentum part of the spectrum is for the characterization of the properties of the created medium. It points, as well, to interesting properties of the nuclear wave function at small f...

Event – by – event fluctuations in heavy – ion collisions and the quark – gluon string model

We apply dynamical string models of heavy–ions collisions at high energies to the analysis of event–by–event fluctuations. Main attention is devoted to a new variable proposed to study ”equilibration” in heavy–ions collisions. Recent results of the NA49 collaboration at CERN SPS are compared with predictions of the Quark–Gluon String Model (QGSM), which gives a good description of different asp...

Hard Thermal Loops , Quark - Gluon Plasma Response

I outline various derivations of the non-Abelian Kubo equation, which governs the response of a quark-gluon plasma to hard thermal perturbations. In the static case, it is proven that gauge theories do not support hard thermal solitons. Explicit solutions are constructed within an SU (2) Ansatz and they are shown to support the general result. The time-dependent problem, i.e., non-Abelian plasm...
