Higgs Cosmology and Dark Matter
Ian G. Moss, Ruth Gregory
TL;DR
This paper explores how Higgs vacuum stability influences cosmology, suggesting that metastability constrains dark matter composition and proposing Higgs decay as a potential source of primordial black holes during inflation.
Contribution
It presents new constraints on dark matter black holes based on Higgs vacuum metastability and introduces the idea that Higgs decay could generate primordial black holes.
Findings
Dark matter cannot contain black holes lighter than 10^{15} g within our past light cone.
Higgs vacuum decay may produce primordial black holes during inflation.
Metastability of the Higgs vacuum imposes cosmological constraints.
Abstract
Higgs vacuum stability has important consequences for cosmology. In particular, we argue that if the Higgs vacuum is metastable, then the dark matter cannot contain a single black hole of mass less than in our entire past light cone. In addition to being the destroyer microscopic black holes, it may be possible that Higgs vacuum decay is a source of primordial black holes during inflation.
