Lepton Flavour Asymmetries and the Mass Spectrum of Primordial Black Holes
arXiv:2011.07283 · doi:10.1103/PhysRevD.103.063506
Abstract
We study the influence of lepton flavour asymmetries on the formation and the mass spectrum of primordial black holes. We estimate the detectability of their mergers with LIGO/Virgo and show that the currently published gravitational wave events may actually be described by a primordial black hole spectrum from non-zero asymmetries. We suggest to use gravitational-wave astronomy as a novel tool to probe how lepton flavour asymmetric the Universe has been before the onset of neutrino oscillations.
