Probing the Particle Spectrum of Nature with Evaporating Black Holes

TL;DR

Observing evaporating black holes could reveal detailed information about the particle spectrum of nature, including potential new physics beyond the Standard Model, by analyzing the emitted photons.

Contribution

This paper demonstrates how black hole evaporation observations can constrain dark sector models and explore physics beyond the Standard Model up to 100 TeV.

Findings

Black hole radiation can probe particle models up to 100 TeV.

Observation at 0.01 parsecs can detect multiple Standard Model copies.

Photon spectra provide insights into the particle content of the universe.

Abstract

Photons radiated from an evaporating black hole in principle provide complete information on the particle spectrum of nature up to the Planck scale. If an evaporating black hole were to be observed, it would open a unique window onto models beyond the Standard Model of particle physics. To demonstrate this, we compute the limits that could be placed on the size of a dark sector. We find that observation of an evaporating black hole at a distance of 0.01 parsecs could probe dark sector models containing one or more copies of the Standard Model particles, with any mass scale up to 100 TeV.
