- Abstract
- This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. Collective behavior, indicating a QGP phase, is studied through anisotropic flow coefficients.
While small collision systems like pp were considered benchmarks, collective phenomena question this perception, suggesting the formation of a QGP in smaller systems. This thesis introduces a novel method to detect flow in those systems.

- This thesis dives into the heart of matter, exploring the building blocks of our universe by focusing on the transition from Quantum Chromodynamic matter to a Quark Gluon Plasma (QGP), a state where quarks and gluons roam freely.
This QGP is a hot and dense soup of fundamental particles that expands in a fascinating manner reminiscent of a fluid. By studying how this plasma flows, scientists can uncover clues about its behavior and the conditions that led to its formation, as well as the formation of our Universe.
Traditionally, it was believed that only big collisions could create this exotic state of matter. However, recent findings challenge this belief, suggesting that even small collision systems, like proton-proton, can produce...

This QGP is a hot and dense soup of fundamental particles that expands in a fascinating manner reminiscent of a fluid. By studying how this plasma flows, scientists can uncover clues about its behavior and the conditions that led to its formation, as well as the formation of our Universe.
Traditionally, it was believed that only big collisions could create this exotic state of matter. However, recent findings challenge this belief, suggesting that even small collision systems, like proton-proton, can produce a QGP. To catch these elusive signals of the formation of a QGP, researchers are developing innovative techniques.
This thesis unveils the results of these efforts, showcasing the use of methods like the Event Plane Method and the Cumulant Method, alongside a brand-new approach developed during this Master's project. Through these methods, we have detected telltale signs of flow and anti-flow in proton-proton collisions, hinting at the presence of a miniature QGP.
In essence, this work peels back the layers of the subatomic world, revealing the intricate dance of particles and the surprising formations that emerge from their interactions, offering a glimpse into the mysteries of the universe at its most fundamental level. (Less)
