Soft leptogenesis is a scenario in which the cosmic baryon asymmetry isproduced from a lepton asymmetry generated in the decays of heavy sneutrinos(the partners of the singlet neutrinos of the seesaw) and where the relevantsources of CP violation are the complex phases of soft supersymmetry-breakingterms. We explain the motivations for soft leptogenesis, and review its basicingredients: the different CP-violating contributions, the crucial role playedby thermal corrections, and the enhancement of the efficiency from leptonflavour effects. We also discuss the high temperature regime $T > 10^7$ GeV inwhich the cosmic baryon asymmetry originates from an initial asymmetry of ananomalous $R$-charge, and soft leptogenesis reembodies in $R$-genesis.
