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.…
Galileon inflation
Clare Burrage, Claudia de Rham, David Seery +1
Galileon inflation is a radiatively stable higher derivative model of inflation. The model is determined by a finite number of relevant operators which are protected by a covariant…
Moment transport equations for the primordial curvature perturbation
David J. Mulryne, David Seery, Daniel Wesley
In a recent publication, we proposed that inflationary perturbation theory can be reformulated in terms of a probability transport equation, whose moments determine the correlation…
Infrared effects in inflationary correlation functions
David Seery
In this article, I briefly review the status of infrared effects which occur when using inflationary models to calculate initial conditions for a subsequent hot, dense plasma phase…
Non-gaussianity in axion Nflation models
Soo A Kim, Andrew R Liddle, David Seery
We study perturbations in the multi-field axion Nflation model, taking account of the full cosine potential. We find significant differences with previous analyses which made a qua…
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…
Revisiting fifth forces in the Galileon model
Clare Burrage, David Seery
A Galileon field is one which obeys a spacetime generalization of the non-relativistic Galilean invariance. Such a field may possess non-canonical kinetic terms, but ghost-free the…
