  The nature of dark matter and the origin of the baryon asymmetry are two of
the deepest mysteries of modern particle physics. In the absence of hints
regarding a possible solution to these mysteries, many approaches have been
developed to tackle them simultaneously leading to very diverse and rich
models. We give a short review where we describe the general features of some
of these models and an overview on the general problem. We also propose a
diagrammatic notation to label the different models.
