New experimental approaches in the search for axion-like particles

IG Irastorza, J Redondo - Progress in Particle and Nuclear Physics, 2018 - Elsevier
Axions and other very light axion-like particles appear in many extensions of the Standard
Model, and are leading candidates to compose part or all of the missing matter of the …

Tests of chameleon gravity

C Burrage, J Sakstein - Living reviews in relativity, 2018 - Springer
Theories of modified gravity, where light scalars with non-trivial self-interactions and non-
minimal couplings to matter—chameleon and symmetron theories—dynamically suppress …

Direct detection of dark energy: The XENON1T excess and future prospects

S Vagnozzi, L Visinelli, P Brax, AC Davis, J Sakstein - Physical Review D, 2021 - APS

Solar chameleons: Novel channels

T O'Shea, AC Davis, M Giannotti, S Vagnozzi… - Physical Review D, 2024 - APS
We revisit the flux of chameleons (light scalar particles which could play a role in the dark
energy phenomenon) produced in the interior of the Sun. Our novel analysis incorporates …

Recoil imaging for directional detection of dark matter, neutrinos, and physics beyond the Standard Model

CAJ O'Hare, D Loomba, K Altenmüller… - Proceedings of the US …, 2022 - cris.fbk.eu
