The bulk nuclear matter produced in heavy ion collisions carries a multitude of conserved quantum numbers: electric charge, baryon number, and strangeness. Therefore, the diffusion processes associated to these conserved charges cannot occur independently and must be described in terms of a set of coupled diffusion equations. This physics is implemented by replacing the traditional diffusion coefficients for each conserved charge by a diffusion coefficient matrix, which quantifies the coupling… Expand

Diffusion of Conserved Charges in Relativistic Heavy Ion Collisions.
It is demonstrated that the diffusion currents do not depend only on gradients of their corresponding charge density, but that the different diffusion charge currents are coupled, and the baryon diffusion current is strongly affected by bARYon charge gradients but also by its coupling to gradients in strangeness.
