Description
This presentation introduces a cosmological mechanism featuring a spectator field and investigates its connection to the formation of primordial black holes (PBHs) and dark matter. By considering fluctuations during inflation, we study a natural PBH formation process that doesn’t rely on exotic physics in the potential and the fine-tuning issue can be avoided. Observational constraints demonstrate the mechanism’s ability to reproduce PBH abundance and mass distribution. This mechanism can be applied in a variety of theoretical framework and it can give us remarkable results.
