Sumario:From subatomic particles to the Big Bang, Quantum Chromodynamics has proven to be one of the milestones for the comprehension of the Universe. A connection between these two regimes is achieved when exploring matter in extreme conditions, which is studied in the world’s largest colliders by crashing nuclei at very high energies. These experiments generate a new state of matter called Quark-Gluon Plasma (QGP), whose formation process is the topic of this thesis. By introducing the kinetic theory as a weak-coupling tool to study the thermalization of the system created after ion collisions, we can quantitatively investigate the formation of the QGP. We propose two novel computational tools to solve the kinetic equations: one based on GPU calculations and another incorporating machine learning techniques.
