Introduction to leptogenesis
arXiv:hep-ph/0702199
Abstract
The discovery of neutrino masses makes leptogenesis a very attractive scenario for explaining the puzzle of the baryon asymmetry of the Universe. We present the basic ingredients of leptogenesis, explain the predictive power of this scenario (and its limitations), and describe recent theoretical developments.
