Abstract

Recently various string inspired models have gained a lot of interest not only because of the second string revolution but also because of the possibility to discover new physics with the future experiments at the 1 TeV scale. In the context of the two-Higgs extension of the SM, the charge violating cosmological phase does not produce a net charge asymmetry. However if the spectrum contains heavy leptons it is possible to create a net cosmic charge asymmetry. This asymmetry can lead to dramatic effects in the cosmological evolution due to the large strength of the electromagnetic interactions as compared to those of gravity. Any specific model that produces a charge asymmetry beyond a certain limit can be ruled out on cosmological grounds
