Dyonic lattices, -angles and axions in the Standard Model
Rodrigo Alonso, Francesca Chadha-Day, Despoina Dimakou +2
We investigate the implications of the Witten effect in the Standard Model with a general global gauge group structure and determine the values of the three -parameters that le…
Discovering the Axiverse via Fifth Forces
Martin Bauer, Francesca Chadha-Day, Alexander Eberhart
If the Universe is described by string theory or other extensions of the Standard Model, several light, axion-like states are predicted to exist. However, most experiments only sea…
Searching for axions with time resolved pulsar polarimetry
Francesca Chadha-Day, Tanmay Kumar Poddar
Pulsars possess strong dipole magnetic fields that can source axion fields through the axion-photon interaction. Pulsars may therefore be surrounded by axion field configurations o…
WISPedia -- the WISPs Encyclopedia
Conrado Albertus, Francesca Chadha-Day, Arturo de Giorgi +8
The Weakly-Interacting Slim Particle encyclopedia (WISPedia) is a comprehensive reference work dedicated to the systematic compilation of theoretical models, Effective Field Theori…
Axion superradiance
Francesca Chadha-Day
Light bosonic fields may suffer an instability around a rotating compact object. This process, known as superradiance, leads to the exponential amplification of the field around a…
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…
