Stability in Axion Inflation with Strong Backreaction from a Massive Vector Boson
Michael J. Baker, Joaquim Iguaz Juan, Lorenzo Sorbo
We study a modification of the model of axion inflation coupled to a gauge field where the vector field is massive. In the conventional scenario with a massless gauge field,…
High-energy neutrino constraints on primordial black holes as dark matter
Mainak Mukhopadhyay, Joaquim Iguaz Juan
Primordial black holes (PBHs) are one of the most appealing dark matter candidates over a wide range of masses and abundances. This broad parameter space has been constrained by a…
Probing Dark Sectors with Exploding Black Holes: Gamma Rays
Michael J. Baker, Joaquim Iguaz Juan, Aidan Symons +1
The Hawking radiation from the explosion of a black hole would provide definitive information on the particle spectrum of nature. Here we quantify the potential of current and futu…
Baryogenesis via Asymmetric Evaporation of Primordial Black Holes
Joaquim Iguaz Juan, Yuber F. Perez-Gonzalez, Jessica Turner
We revisit baryogenesis from the asymmetric evaporation of light primordial black holes, focusing on scenarios where gravitational effects induce a matter antimatter asymmetry. In…
Explaining the PeV Neutrino Fluxes at KM3NeT and IceCube with Quasi-Extremal Primordial Black Holes
Michael J. Baker, Joaquim Iguaz Juan, Aidan Symons +1
The KM3NeT experiment has recently observed a neutrino with an energy around 100PeV, and IceCube has detected five neutrinos with energies above 1PeV. While there are no known astr…
Primordial black hole formation from self-resonant preheating?
Guillermo Ballesteros, Joaquim Iguaz Juan, Paquale D. Serpico +1
We revisit the question of how generic is the formation of primordial black holes via self-resonant growth of inflaton fluctuations in the post-inflationary, preheating phase. Usin…
