Non-Gaussianity constrains hybrid inflation
David Mulryne, David Seery, Daniel Wesley
In hybrid inflationary models, inflation ends by a sudden instability associated with a steep ridge in the potential. Here we argue that this feature can generate a large contribut…
Higgs production as a probe of Chameleon Dark Energy
Philippe Brax, Clare Burrage, Anne-Christine Davis +2
In this paper we study various particle physics effects of a light, scalar dark energy field with chameleon-like couplings to matter. We show that a chameleon model with only matte…
Collider constraints on interactions of dark energy with the Standard Model
Philippe Brax, Clare Burrage, Anne-Christine Davis +2
We study models in which a light scalar dark energy particle couples to the gauge fields of the electroweak force, the photon, Z and W bosons. Our analysis applies to a large class…
Non-Gaussianity as a Probe of the Physics of the Primordial Universe and the Astrophysics of the Low Redshift Universe
E. Komatsu, N. Afshordi, N. Bartolo +58
A new and powerful probe of the origin and evolution of structures in the Universe has emerged and been actively developed over the last decade. In the coming decade, non-Gaussiani…
