Heavy flavour azimuthal correlations from small to large systems

Abstract

Studying the ultra-relativistic heavy-ion collisions with the A Large Ion Collider Experiment (ALICE) at the Large Hadron Collider(LHC) at European Council for Nuclear Research (CERN) is like peering into the early universe [8–13]. It is believed that in the early universe, some microseconds after the Big Bang, a new state of matter is formed called the quark-gluon plasma (QGP), where quarks and gluons exist as free particles rather than being confined inside hadrons. This state of matter is believed to exist before forming the hadrons. ALICE experiment aims to create and explore the properties of such state, i.e., temperature, energy density, viscosity, and the behavior of quarks and gluons within the medium.
