Anomalous coupling of scalars to gauge fields
Philippe Brax, Clare Burrage, Anne-Christine Davis +2
We study the transformation properties of a scalar-tensor theory, coupled to fermions, under the Weyl rescaling associated with a transition from the Jordan to the Einstein frame.…
The Chameleonic Contribution to the SZ Radial Profile of the Coma Cluster
Anne-Christine Davis, Camilla A. O. Schelpe, Douglas J. Shaw
We constrain the chameleonic Sunyaev--Zel'dovich (CSZ) effect in the Coma cluster from measurements of the Coma radial profile presented in the WMAP 7-year results. The CSZ effect…
The Dilaton and Modified Gravity
Philippe Brax, Carsten van de Bruck, Anne-Christine Davis +1
We consider the dilaton in the strong string coupling limit and elaborate on the original idea of Damour and Polyakov whereby the dilaton coupling to matter has a minimum with a va…
Preheating in Dirac-Born-Infeld inflation
Nazim Bouatta, Anne-Christine Davis, Raquel H. Ribeiro +1
We study how the universe reheats following an era of chaotic Dirac-Born-Infeld inflation, and compare the rate of particle production with that in models based on canonical kineti…
Tuning the Mass of Chameleon Fields in Casimir Force Experiments
Ph. Brax, C. van de Bruck, A. C. Davis +2
We have calculated the chameleon pressure between two parallel plates in the presence of an intervening medium that affects the mass of the chameleon field. As intuitively expected…
