Theories of modified gravity, where light scalars with non-trivial self-interactions and non-
minimal couplings to matter—chameleon and symmetron theories—dynamically suppress …

During 2003--2015, the CERN Axion Solar Telescope (CAST) has searched for $
a\to\gamma $ conversion in the 9 T magnetic field of a refurbished LHC test magnet that can …

The CAST-CAPP axion haloscope, operating at CERN inside the CAST dipole magnet, has
searched for axions in the 19.74 μ eV to 22.47 μ eV mass range. The detection concept …

Hypothetical low-mass particles, such as axions, provide a compelling explanation for the
dark matter in the universe. Such particles are expected to emerge abundantly from the hot …

If dark energy, which drives the accelerated expansion of the universe, consists of a light
scalar field, it might be detectable as a “fifth force” between normal-matter objects, in …

Various theories have been proposed for the nature of dark energy. It is therefore essential
to directly verify or rule out these theories by experiment. Despite substantial efforts in …

Constraints on selected mediator-based dark matter models and a scalar dark energy model
using up to $37~\mathrm {fb}^{-1} $$\sqrt s= 13$ TeV $ pp $ collision data collected by the …

We explore the prospects for direct detection of dark energy by current and upcoming
terrestrial dark matter direct detection experiments. If dark energy is driven by a new light …

Hypothetical axions provide a compelling explanation for dark matter and could be emitted
from the hot solar interior. The CERN Axion Solar Telescope has been searching for solar …

We present a proposal for a new experiment, the FINUDA magnet for Light Axion SearcH
(FLASH), a large resonant-cavity haloscope in a high static magnetic field which is planned …
