Some aspects of primordial black hole physics

Abstract : Small black holes should have formed in the early Universe if the density contrast was high enough. This article aims at giving a - biased and partial - short overview of the latest breakthroughs in this field. It first deals with tentative experimental detections thanks to gamma-rays and cosmic-rays. Primordial black holes (PBHs) are then considered as probes of the very small cosmological scales, far beyond any other classical observable. Finally, some possible "new physics" effects are considered, especially in the framework of higher dimensions.
