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…

Axionic defects in the CMB: birefringence and gravitational waves
Ricardo Z. Ferreira, Silvia Gasparotto, Takashi Hiramatsu +2
The evidence for a non-vanishing isotropic cosmic birefringence in recent analyses of the CMB data provides a tantalizing hint for new physics. Domain wall (DW) networks have recen…

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…
