New bounds on Memory Burdened Primordial Black Holes from Big Bang Nucleosynthesis

2025 · arXiv (Cornell University)

Primordial black holes (PBHs) with masses below $10^9\,\rm{g}$ are typically assumed to have negligible cosmological impact due to their rapid evaporation via Hawking radiation. However, the 'memory burden' effect, which is a quantum suppression of …
