Physics Beyond the Standard Model with BlackHawk v2.0

TL;DR

BlackHawk v2.0 is an advanced computational tool that models Hawking radiation from black holes, incorporating new physics beyond the Standard Model such as dark matter emission and BSM metrics, enabling detailed cosmological and particle physics studies.

Contribution

The paper introduces BlackHawk v2.0, a significantly upgraded code with new features for BSM physics, including dark matter emission, spin 3/2 greybody factors, and BSM black hole metrics.

Findings

Added dark matter and dark radiation emission capabilities

Implemented spin 3/2 greybody factors and BSM black hole metrics

Enhanced low energy secondary particle showering treatment

Abstract

We present the new version v2.0 of the public code BlackHawk designed to compute the Hawking radiation of black holes, with both primary and hadronized spectra. This new version aims at opening an avenue toward physics beyond the Standard Model (BSM) in Hawking radiation. Several major additions have been made since version v1.0: dark matter/dark radiation emission, spin $3/2$ greybody factors, scripts for cosmological studies, BSM black hole metrics with their associated greybody factors and a careful treatment of the low energy showering of secondary particles; as well as bug corrections. We present, in each case, examples of the new capabilities of BlackHawk.
