# Primordial Black Holes as Silver Bullets for New Physics at the Weak Scale

## TL;DR

This paper discusses how detecting primordial black holes through radio and gravitational wave searches could impose strict constraints on weak-scale extensions of the Standard Model, potentially ruling out many dark matter theories.

## Contribution

It demonstrates that upcoming PBH searches can significantly constrain or exclude broad classes of weak-scale new physics models, including popular supersymmetric and scalar dark matter theories.

## Key findings

- Radio and gravitational wave searches can detect PBHs or set constraints.
- Detection prospects could rule out large parts of supersymmetric models.
- PBH observations can test and constrain weak-scale physics theories.

## Abstract

Observational constraints on gamma rays produced by the annihilation of weakly interacting massive particles around primordial black holes (PBHs) imply that these two classes of Dark Matter candidates cannot coexist. We show here that the successful detection of one or more PBHs by radio searches (with the Square Kilometer Array) and gravitational waves searches (with LIGO/Virgo and the upcoming Einstein Telescope) would set extraordinarily stringent constraints on virtually all weak-scale extensions of the Standard Model with stable relics, including those predicting a WIMP abundance much smaller than that of Dark Matter. Upcoming PBHs searches have in particular the potential to rule out almost the entire parameter space of popular theories such as the minimal supersymmetric standard model and scalar singlet Dark Matter.
