Flow analysis with Gapped Q-Cumulants

Abstract

Anisotropic flow is an important observable in the study of the Quark-Gluon Plasma that is expected to be formed in heavy-ion collisions. Non-flow contributions caused by particle decay, jets and track splitting can bias flow measurements. This thesis describes the addition of an eta-gap to the existing Q-Cumulants method to suppress non-flow. This so-called Gapped Q-Cumulants method is tested with Monte Carlo simulations and shown to be succesful in suppressing the non-flow contributions.
