Description
The Quark-Gluon Plasma, a new state of matter characterized by its extreme energy density
and temperature generated in heavy-ion collision experiments, is expected to modify hard-scattered
partons traveling through it and, consequently, the jets they produce. Analyses regarding jets
may recover information about the medium and its partonic energy-loss mechanism. This work
applies the Monte Carlo event generators JEWEL and PYTHIA for the simulation of observables
comparable to current experimental research, focusing on the impact of a realistic description of the
medium, provided by the state-of-the-art (2+1)D v-USPhydro code, in the azimuthal distribution
and energy modification of jets.
We present the jet nuclear modification factor RAA and anisotropic flow coefficients vn=2,3,4 for
multiple models, centralities and jet radii R. The RAA simulated presents good agreement with
experimental data for central collisions only. The evolution of the results in terms of centrality and
R indicates a possibility of better understanding of medium response in the JEWEL framework. The
realistic hydrodynamics models behave differently to JEWEL’s longitudinal-only expansion, mainly
in the circumstances where less quenching is expected. The correlation between the jet azimuthal
distribution and those generated by soft particles resulted from the realistic medium profiles enables
the event-by-event calculation of higher-order jet anisotropic flow coefficients that can be compared
to experimental measurements. The simulations show a transverse momentum-dependent elliptic
flow v2 and, for the first time, a positive triangular flow v3 .
