Axion Inflation with a Massive Abelian Gauge Field
Ricardo Z. Ferreira, Alessio Notari, José Jaime Terente DÃaz
The paper studies how an axial coupling between an inflaton (axion) and a massive Abelian gauge field can cause tachyonic amplification of one helicity, analyzes the resulting back…

Spectator Axions in String Inflation and Primordial Black Holes
Michele Cicoli, Dario L. Lorenzoni, Evan McDonough +1
The paper examines how light spectator axions during Fibre Inflation in string theory influence the generation of primordial black holes, showing that axions with moderately large…

A multi-axion model of inflation and dark matter
Marcos A. G. Garcia, Hansel Gordillo-Ruiz, Raul Henriquez-Ortiz +1
The paper proposes a multi-axion framework arising from extra dimensions where the heaviest axion drives inflation and the lighter axions later behave as dynamical dark matter, mat…
