Description

We present a novel hydrodynamic model of nuclear collisions in which baryon number, electric charge, and strangeness diffuse as coupled currents governed by the conductivity matrix [1], using a lattice-based four-dimensional QCD equation of state. Baryon diffusion transports net baryons toward midrapidity with growing strength at lower beam energies, while net strangeness develops a wave-like rapidity structure from strangeness-neutral initial conditions. We show that emulator-based inversion of identified particle yields across RHIC beam energy scan energies constrains most of the conductivity matrix.
