Evolving Charge Correlations in a Hybrid Model with both Hydrodynamics and Hadronic Boltzmann Descriptions

Understand

Correlations related to local charge conservation provide insight into the creation and evolution of up, down and strange charges in the quark-gluon plasma.

• Here, the evolution of charge correlations is overlaid onto a hydrodynamic calculation for the regions where temperature exceed 155 MeV, then transferred and carried through a microscopic model of the hadronic stage.
• Thus, for the first time, charge correlations are evolved consistently with a full state-of-the-art description of a heavy-ion collision.
• The charge correlations are projected onto charge balance functions, which characterize such correlations in the final state, and are presented as a function of relative rapidity and relative azimuthal angle for Au/Au collisions.
