Description

Ultra-relativistic heavy ion collisions, such as those in the Large Hadron Collider (LHC) or the Relativistic Heavy-Ion Collider (RHIC), have unlocked an extensive scientific program. Namely, the production of Quark-Gluon Plasma (QGP) offers many opportunities, from the study of early universe dynamics, to the phase diagram of Quantum Chromodynamics (QCD), and the study of QCD in extreme conditions.
Given the rapid evolution of the QGP, on the yoctosecond scale, its properties are accessed through the products of heavy ion collisions. The successive parton showers can be explored by the clustering of the final state hadrons into jets. This allows for the study of jet quenching in the QGP, which can be used to access the medium evolution.
As seen in recent developments, jet clustering algorithms can be used to access the space-time structure of the parton showers, unlocking an experimental treatment of the medium evolution. However, theoretical descriptions rest on the use of coordinate space while event generators, used for phenomenological studies, reflect the momentum space evolution of parton showers.
The aim of this work is therefore to develop a simple Monte Carlo Event Generator in coordinate space, paving the way to a full treatment of QCD showers and their modification by the presence of the QGP.
