Flow in small systems in the EPOS4 approach for high-energy scattering
Year: 2025
Type: article
Abstract: EPOS4 is based on a sophisticated (recently significantly improved) parallel-primary-scattering scenario followed by a hydrodynamic expansion, for all collision systems, from small ones such as proton-proton ( p p ) to large ones such as lead-lead (PbPb). Having already reported on identified particle spectra in recent publications (providing information about radial flow), I discuss here the multiplicity dependence of multiparticle cumulants and flow harmonics, to better understand collectivity in small systems. The model is not particularly tuned for flow results, but it is a “general purpose” approach, trying to accommodate various types of observables with the same model.
