Lepton Asymmetry of the Universe and Charged Quark-Gluon Plasma

Abstract

The lepton asymmetry of order one is not excluded experimentally and, if present, can lead to interesting phenomena in the early Universe. It is shown that, when the temperature is above the quark-hadron transition, the lepton asymmetry induces chemical potentials for electric charge and for baryon number, and makes the quark-gluon plasma electrically charged.
