Clustering Corrections to Primordial Black Hole Abundance Bounds

Year: 2026

Type: article

Abstract: Almost every abundance bound in the primordial black hole literature is derived as if the holes were distributed smoothly, or at most Poisson-randomly, through the dark matter halo. Formation physics does not promise that. The headline computed values are: lens relax N1000 = 5.62; merge tight N1000 = 31.6. All quantities are computed from the stated assumptions; nothing in the study is a measurement, and the full calculation is deposited for independent checking.
