Multi-Field Dilaton Screening Beyond the Thin-Shell Mechanism
Philippe Brax, Carsten van de Bruck, Anne-Christine Davis +1
We analyse screening in multi-field scalar-tensor theories, focusing on systems with a dilaton coupled to matter and an axion with a dilaton-dependent kinetic term, in the presence…
Illuminating the dark universe in the multi-messenger era
Philippe Brax, Anne-Christine Davis, Md Riajul Haque +8
The precision era of multi-messenger astronomy, together with modern astrophysical, cosmological, and gravitational wave observations, increasingly points toward the existence of a…
Improved Search for Solar Chameleons with a GridPix Detector at CAST
V. Anastassopoulos, S. Aune, K. Barth +66
We report on a new search for solar chameleons with the CERN Axion Solar Telescope (CAST). A GridPix detector was used to search for soft X-ray photons in the energy range from 200…
D-term Uplifted Racetrack Inflation
Philippe Brax, Anne-Christine Davis, Stephen C. Davis +2
It is shown that racetrack inflation can be implemented in a moduli stabilisation scenario with a supersymmetric uplifting D-term. The resulting model is completely described by an…
A Chameleon Primer
Ph. Brax, C. van de Bruck, A. C. Davis
We review some of the properties of chameleon theories. Chameleon fields are gravitationally coupled to matter and evade gravitational tests thanks to two fundamental properties. T…
Cosmic D-Strings and Vortons in Supergravity
Ph. Brax, C. van de Bruck, A. C. Davis +1
Recent developments in string inspired models of inflation suggest that D-strings are formed at the end of inflation. Within the supergravity model of D-strings there are 2(n-1) ch…
