Physics:Quantum data analysis/Event Flows
Event flows describe collective patterns in the angular distribution of particles produced in a collision. The term is especially important in heavy-ion physics, where anisotropic flow coefficients quantify how the collision geometry and medium response shape final-state particle emission. Flow observables are also useful as event-shape variables in broader collider analyses.[1]
Flow coefficients
Azimuthal distributions can be expanded in Fourier coefficients such as directed, elliptic, and triangular flow. These coefficients summarize collective angular structure in a way that can be compared across centrality, momentum, and particle species.[1]
Measurement methods
Flow measurements use event-plane, scalar-product, cumulant, and correlation techniques. Each method has different sensitivity to nonflow correlations, detector acceptance, and event-by-event fluctuations.[2]
Interpretation
In heavy-ion collisions, flow is interpreted as evidence for collective behavior and transport properties of strongly interacting matter. In smaller systems, flow-like signals require careful comparison with jets, resonance decays, and other correlations.[3]
