Beschreibung
The $R$-dependence of jet observables provides a new tool in understanding the interplay between the jet energy-loss mechanism and medium response in heavy-ion collisions. We have coupled the Monte Carlo event generators JEWEL and PYTHIA, with initial conditions from the $\rm T_RENTo$ and the state-of-the-art (2+1)D v-USPhydro, for the simulation of jet quenching phenomena in a more realistic medium formed in lead-lead collisions at LHC energy scales.
In this work, we present one of the first studies of the jet nuclear modification $R_{AA}$ and anisotropic flow coefficients $v_{n=2,3}$ as a function of the jet cone radius $R$, in the context of anti-$k_T$ jets, in addition to jet shape observables. The calculations indicate the impacts of the hydrodynamic evolution and weakly-coupled medium response, given by recoils, on the distributions. Results are compared to experimental data in a wide range of jet $p_T$ and collision centrality, and displayed along with large jets ($R \ge 0.6$) predictions.
