Medium modification of jet shape observables in Pb-Pb collisions at $\sqrt{s_{NN}}$= 2.76 TeV using EPOS and JEWEL event generators

TL;DR

This study investigates how the internal structure of charged jets is altered in central Pb-Pb collisions at 2.76 TeV, providing insights into jet quenching and energy loss mechanisms in quark-gluon plasma.

Contribution

It presents a model-dependent analysis of jet shape modifications using EPOS and JEWEL generators, focusing on differential jet shape and angularity in heavy-ion collisions.

Findings

Jet substructure is significantly modified in Pb-Pb collisions.

Energy redistribution within jets indicates medium-induced effects.

Results help constrain models of jet quenching mechanisms.

Abstract

The substructure of charged jets gets modified due to the presence of the medium in heavy-ion collisions which is an indication of redistribution of energy inside the jet cone. It helps to understand the energy loss mechanisms of jets in the medium. A model dependent study of the modification of differential jet shape $(\rho(r))$ and the angularity (g) due to medium, has been performed in the most central Pb-Pb collisions at 2.76 TeV in the jet range of 20-40 GeV/c.
