Amnesia in the Axion Misalignment Landscape
Kierthika Chathirathas, Cem Eröncel, Mathieu Kaltschmidt +2
Pre-inflationary axion cosmologies admit a broad range of initial velocities and angles that generate a landscape of misalignment histories, whose nonlinear fate and small-scale st…
Axions at the meV Crossroads: Theory, Cosmology, Astrophysics, and Experiments
Michele Cicoli, Francesco D'Eramo, Luca Di Luzio +18
The meV mass range has emerged as a focal point in axion physics, where advances in theory, cosmology, astrophysics, and experimental techniques converge. Axions in this mass range…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Probing the Axion-Nucleon Coupling with Supergiant Stars
Francisco R. Candón, Pablo Casaseca, Maurizio Giannotti +3
A finite axion-nucleon coupling enables the production of axions in stellar environments via the thermal excitation and subsequent de-excitation of the Fe isotope. Given its…
Detecting Supernova Axions with IAXO
P. Carenza, J. A. GarcÃa Pascual, M. Giannotti +8
We investigate the potential of IAXO and its intermediate version, BabyIAXO, to detect axions produced in core-collapse supernovae (SNe). Our study demonstrates that these experime…
Exploring the Dark Universe: A European Strategy for Axions and other WISPs Discovery
Deniz Aybas, Francesca Calore, Michele Cicoli +17
Axions and other very weakly interacting slim (with 1 GeV) particles (WISPs) are a common feature of several extensions of the Standard Model of Particle Physics. The search…
