Detuning primordial black hole dark matter with early matter domination and axion monodromy
Guillermo Ballesteros, Julián Rey, Fabrizio Rompineve
We present a scenario that ameliorates the tuning problems present in models of primordial black hole dark matter from inflation. Our setup employs the advantages of gravitational…
X-ray and gamma-ray limits on the primordial black hole abundance from Hawking radiation
Guillermo Ballesteros, Javier Coronado-Blázquez, Daniele Gaggero
The non-observation of Hawking radiation from primordial black holes of g sets a conservative strong bound on their cosmological abundance. We revisit this bound and show…
Several Problems in Particle Physics and Cosmology Solved in One SMASH
Guillermo Ballesteros, Javier Redondo, Andreas Ringwald +1
The Standard Model (SM) of particle physics is a big success. However, it lacks explanations for cosmic inflation, the matter-anti-matter asymmetry of the Universe, dark matter, ne…
