Relaxion Fluctuations (Self-stopping Relaxion) and Overview of Relaxion Stopping Mechanisms
Nayara Fonseca, Enrico Morgante, Ryosuke Sato +1
In implementations of the electroweak scale cosmological relaxation mechanism proposed so far, the effect of the quantum fluctuations of the homogeneous relaxion field has been ign…
Axion Fragmentation
Nayara Fonseca, Enrico Morgante, Ryosuke Sato +1
We investigate the production of axion quanta during the early universe evolution of an axion-like field rolling down a wiggly potential. We compute the growth of quantum fluctuati…
Baryogenesis from axion inflation
Valerie Domcke, Benedict von Harling, Enrico Morgante +1
The coupling of an axion-like particle driving inflation to the Standard Model particle content through a Chern-Simons term generically sources a dual production of massless helica…
