CHEMICALS POTENTIAL IN THE ELECTROWEAK STANDARD MODEL

In the context of thermal quantum field theory are introduced three chemical potentials associated to the three conserved currents in the Electroweak Standard Model: electromagnetic, weak neutral and lepton number. The neutrality condition over electromagnetic and weak neutral charges is calculated by mean thermodynamic potential. The calculations are done using the mean field approximation at high temperature limit.
