SUPER-Screening
Philippe Brax, Anne-Christine Davis, Jeremy Sakstein
We present a framework for embedding scalar-tensor models of screened modifed gravity such as chameleons, symmetrons and environmental dilatons into global supersymmetry. This achi…
Screening fifth forces in k-essence and DBI models
Philippe Brax, Clare Burrage, Anne-Christine Davis
New fifth forces have not yet been detected in the laboratory or in the solar system, hence it is typically difficult to introduce new light scalar fields that would mediate such f…
Shining Light on Modifications of Gravity
Philippe Brax, Clare Burrage, Anne-Christine Davis
Many modifications of gravity introduce new scalar degrees of freedom, and in such theories matter fields typically couple to an effective metric that depends on both the true metr…
Decoupling Survives Inflation: A Critical Look at Effective Field Theory Violations During Inflation
Anastasios Avgoustidis, Sera Cremonini, Anne-Christine Davis +3
We investigate the validity of effective field theory methods and the decoupling of heavy fields during inflation. Considering models of inflation in which the inflaton is coupled…
