Inflaton Oscillations and Post-Inflationary Reheating

Marcos A. G. Garcia, Kunio Kaneta, Yann Mambrini +1

We analyze in detail the perturbative decay of the inflaton oscillating about a generic form of its potential , taking into account the effects of non-instantaneous reh…

The Impact of New d(p,γ)He3 Rates on Big Bang Nucleosynthesis

Tsung-Han Yeh, Keith A. Olive, Brian D. Fields

We consider the effect on Big Bang Nucleosynthesis (BBN) of new measurements of the He cross section by the LUNA Collaboration. These have an important effect on the pr…

Low-Energy Probes of No-Scale SU(5) Super-GUTs

John Ellis, Jason L. Evans, Natsumi Nagata +2

We explore the possible values of the branching ratio, , and the electron dipole moment (eEDM), , in no-scale SU(5) super-GUT models wit…

Improving Helium Abundance Determinations with Leo P as a Case Study

Erik Aver, Danielle A. Berg, Keith A. Olive +3

Currently, the primordial helium abundance is best estimated through spectroscopic observations of H II regions in metal-poor galaxies. However these determinations are limited by…

Building Models of Inflation in No-Scale Supergravity

John Ellis, Marcos A. G. Garcia, Natsumi Nagata +3

After reviewing the motivations for cosmological inflation formulated in the formalism of supersymmetry, we argue that the appropriate framework is that of no-scale supergravity. W…

Non-Oscillatory No-Scale Inflation

John Ellis, Dimitri V. Nanopoulos, Keith A. Olive +1

We propose a non-oscillatory no-scale supergravity model of inflation (NO-NO inflation) in which the inflaton does not oscillate at the end of the inflationary era. Instead, the Un…
