Hybrid Natural Low Scale Inflation
Graham G Ross, Gabriel German
We discuss the phenomenological implications of hybrid natural inflation models in which the inflaton is a pseudo-Goldstone boson but inflation is terminated by a second scalar fie…
Hybrid natural inflation from non Abelian discrete symmetry
Graham G Ross, Gabriel German
A spontaneously broken global discrete symmetry may have pseudo Goldstone modes associated with the spontaneous breaking of the approximate continuous symmetry of the low dimension…
Low-scale inflation
Gabriel German, Graham Ross, Subir Sarkar
We show that the scale of the inflationary potential may be the electroweak scale or even lower, while still generating an acceptable spectrum of primordial density perturbations.…
Implementing quadratic supergravity inflation
Gabriel German, Graham Ross, Subir Sarkar
We study inflation driven by a slow-rolling inflaton field, characterised by a quadratic potential, and incorporating radiative corrections within the context of supergravity. In t…
