Abstract:

In heavy-ion collisions, the generation of final-state particle spectra is influenced by the collective expansion of the system in the quark-gluon plasma (QGP) phase. This collectivity manifests itself as an anisotropy in the azimuthal distribution measured by the detector, and can experimentally be quantified using the Fourier harmonics v_n. In this seminar, I will present the new results for these harmonics from Run 3 Pb-Pb collisions measured at ALICE, extracted using multiparticle correlation techniques, with a focus on how these observables are related to detector occupancy and interaction rates. Additionally, Monte Carlo simulations can also supplement the analysis by providing insights to the collision's initial geometry, allowing access to the eccentricities of the initial nucleon distributions. Here, I will present initial results obtained using EPOS4, a Monte Carlo simulator for high-energy collisions, for accessing the anisotropies both in position and momentum space.
