The Hubble Tension as a Hint of Leptogenesis and Neutrino Mass Generation

Miguel Escudero, Samuel J. Witte

The majoron, a neutrinophilic pseudo-Goldstone boson conventionally arising in the context of neutrino mass models, can damp neutrino free-streaming and inject additional energy de…

Collider Signals of Baryogenesis and Dark Matter from Mesons: A Roadmap to Discovery

Gonzalo Alonso-Álvarez, Gilly Elor, Miguel Escudero

Low-scale baryogenesis could be discovered at -factories and the LHC. In the -Mesogenesis paradigm [G. Elor, M. Escudero, and A. E. Nelson, PRD 99, 035031 (2019), arXiv:1810.…

New Constraints on the Mass of Fermionic Dark Matter from Dwarf Spheroidal Galaxies

James Alvey, Nashwan Sabti, Victoria Tiki +7

Dwarf spheroidal galaxies are excellent systems to probe the nature of fermionic dark matter due to their high observed dark matter phase-space density. In this work, we review, re…

The Axion Quality Problem: Global Symmetry Breaking and Wormholes

James Alvey, Miguel Escudero

Continuous global symmetries are expected to be broken by gravity, which can lead to important phenomenological consequences. A prime example is the threat that this poses to the v…

The First Three Seconds: a Review of Possible Expansion Histories of the Early Universe

Rouzbeh Allahverdi, Mustafa A. Amin, Asher Berlin +23

It is commonly assumed that the energy density of the Universe was dominated by radiation between reheating after inflation and the onset of matter domination 54,000 years later. W…

Could the Hubble Tension be Pointing Towards the Neutrino Mass Mechanism?

Miguel Escudero, Samuel J. Witte

Local measurements of the Hubble constant currently disagree with the high-precision value that is inferred from the CMB under the assumption of a CDM cosmology. The significanc…
