CMB Spectral Distortions from an Axion-Dark Photon-Photon Interaction
Anson Hook, Gustavo Marques-Tavares, Clayton Ristow
The presence of a plethora of light spin 0 and spin 1 fields is motivated in a number of BSM scenarios, such as the axiverse. The study of the interactions of such light bosonic fi…
Softening the UV without New Particles
Anson Hook, Riccardo Rattazzi
We explore an odd class of QFTs where a hierarchy problem is resolved with new dynamics as opposed to new particles. The essential element of our construction is a pseudo-NG…
Gravitational-wave signatures from reheating
Manuel A. Buen-Abad, Jae Hyeok Chang, Anson Hook
We initiate a study of the gravitational-wave signatures of a phase transition that occurs as the Universe's temperature increases during reheating. The gravitational-wave signatur…
