Braneworld Effective Field Theories--Holography, Consistency and Conformal Effects
Sylvain Fichet
Braneworld theories are often described as low-energy effective field theories (EFTs) featuring an infinitely thin 3-brane and 4D fields exactly localized on it. We investigate whe…
Exotic Spin-Dependent Forces from a Hidden Sector
Alexandria Costantino, Sylvain Fichet, Philip Tanedo
New dynamics from hidden sectors may manifest as long-range forces between visible matter particles. The well-known case of Yukawa-like potentials occurs via the exchange of a sing…
Approximate Symmetries and Gravity
Sylvain Fichet, Prashant Saraswat
There are strong reasons to believe that global symmetries of quantum theories cannot be exact in the presence of gravity. While this has been argued at the qualitative level, esta…
The Warped Dark Sector
Philippe Brax, Sylvain Fichet, Philip Tanedo
Five-dimensional braneworld constructions in anti-de Sitter space naturally lead to dark sector scenarios in which parts of the dark sector vanish at high 4d momentum or temperatur…
Opacity and Effective Field Theory in Anti-de Sitter Backgrounds
Sylvain Fichet
We consider quantum field theory in a five-dimensional anti-de Sitter background, possibly truncated by 4d branes. In the Euclidian version of this space, it is known that propagat…
