SUMMARY:

Speculations suggest that during one of the initial phases of the expanding Universe,
it was composed of a plasma consisting of quarks and gluonsa high-energy deconfined
state of interacting matter.This state, known as the Quark Gluon Plasma (QGP),
operates under Quantum Chromodynamics, where theoretical studies indicate that the
chiral symmetry typically not observed in hadrons is restored. The foreseen emergence
of this extreme led to the construction of the ALICE experiment, primarily aimed at
exploring the QGP and investigating the theory of strong interactions.
Initially, it was believed that the QGP resembled a gas of weakly interacting partons
due to the condition of asymptotic freedom, achieved at increasingly smaller distances
between interacting particles. However, recent evidence has revealed its liquid-like be-
havior, characterized by a fluidic state comprising highly interacting particles in a dis-
sipative medium.
Among the range of observables used to study this strongly interacting medium,
hard probes stand out as one of the most promising aspects to explore. These probes
encompass high-energy processes occurring in the early collision stages, such as heavy
flavor particles and jets. Heavy flavor particles, distinct for their higher mass compared
to the QGP temperature and QCD scales, exhibit differing interaction behaviors from
light quarks. Furthermore, jets, known for losing energy to the medium, affect both the
medium’s properties and the structure and energy of the jets, making them valuable
tools for probing the QGP.
This work centers on utilizing identification of heavy flavor jets as probes to measure
QGP properties, in-medium interactions, and microscopic structure. Our primary focus
lies on the exploration of heavy flavor jets, and the identification ofD0mesons serves
as a method to tag these jets as heavy flavor candidates.To achieve this, we utilize
PYTHIA, FastJet, and ROOT as our analysis tools for simulation, reconstruction, and
subsequent data analysis
