摘要：

We calculate an electrical chemical potential, mu(e), for hadronic matter produced in relativistic collisions of nuclei with (extremely) large atomic numbers. We find mu(e) < 0 which leads to an asymmetry in the pion production (pi-/pi+ > 1) and a difference between positive and negative pion spectra at low transverse momenta.
