Generation of Cosmological Baryon Asymmetry – (B–L)-Genesis –

Abstract

The advent of the standard gauge theory of particle physics is a story of remarkable suceess. Yet it is the view of most particle physicists that it is not the end for the quest of the ultimate microscopic world. Direct experimental hints for physics beyond the standard theory have recently been provided by the discovery of neutrino oscillation. On the theoretical side, there are many unsolved problems, one of which we will explain in this article.
