Sumário do Projecto
In ultra-relativistic heavy-ion collisions at facilities like the Large Hadron Collider (LHC) and Relativistic
Heavy-Ion Collider (RHIC), extreme temperature and density conditions of the early Universe are recreated,
forming the Quark-Gluon Plasma (QGP). Jets — collimated sprays of particles from the fragmentation of
Quantum Chromodynamics (QCD) building blocks — interact with this evolving medium in a phenomenon
known as jet quenching. ChronoQCD aims to harness the QGP temporal evolution as a laboratory to explore
the dynamic processes of jet radiation and evolution.
The project has three core objectives:
1) Time-Dependent Jet Quenching Evolution: Develop a groundbreaking space-time formulation of jet
evolution, integrating vacuum and medium-induced emissions to accurately describe QGP-induced
modifications to jet fragmentation.
2) Bridging QCD Formation Time and QGP Evolution: Provide a detailed characterisation of the QGP’s time
evolution across diverse momentum scales by connecting formation time to QGP proper time, reducing
model dependence, and validating jet-based QGP probes.
3) Exploration of the QCD Time-Axis: Extend the concept of space-time jets beyond traditional heavy-ion
systems to investigate QGP onset conditions in small systems and explore explicit time dependence in QCD
radiation.
This project will provide precise determination of QGP evolution and properties, unveil the elusive preequilibrium
phase, and identify QGP onset conditions. By addressing critical gaps in QCD studies,
ChronoQCD will advance our understanding of the Universe’s building blocks and shape future physics
programs.
