Abstract
The possibility is investigated that the baryon asymmetry of the Universe might have been created at the electroweak phase transition. It is shown that there exists a process which may in certain models with multiple Higgs doublets generate a numerically acceptable asymmetry. This process involves sphalerons and requires strong CP violation at temperatures larger than 1 TeV.Keywords
