Description
We present a full simulation of evolving charge correlations in heavy-ion collisions using a combination of hydrodynamics and a hadronic Boltzmann cascade to model the underlying system evolution. We compute the charge balance functions (CBFs) in both rapidity and azimuthal angle and observe their dependence on several phenomenological parameters in our model. In particular, we observe significant sensitivity in the $K^+K^-$ and $p\bar{p}$ CBFs to the value of the diffusivity of light quarks, suggesting that a comprehensive analysis of heavy-ion observables which includes the CBFs could be sensitive to this previously unmeasured transport coefficient of QCD matter.
