Description

The strongly interacting matter created in high-energy heavy-ion collisions contains a multitude of conserved quantum charges, like the baryon number, strangeness, and electric charge. These conserved charges lead to coupled charge currents, e.g. a baryon diffusion current, strangeness current and electric charge current. In this talk, we briefly present a novel derivation of second-order relativistic dissipative fluid dynamics from the Boltzmann equation for multicomponent reactive mixtures with $N_{\text{spec}}$ particle species and with $N_q$ conserved charges. We will show and discuss the coupled-charge transport, the resulting separation of charge, and the implied baryon-electric or baryon-strangeness correlations in heavy-ion collisions, and argue that such effects may be relevant for programs at the future FAIR and NICA facilities, or for the discussion of the recent isobar run at RHIC.
