Superstring-Inspired Particle Cosmology: Inflation, Neutrino Masses, Leptogenesis, Dark Matter & the SUSY Scale
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +2
We develop a string-inspired model for particle cosmology, based on a flipped SU(5)U(1) gauge group formulated in a no-scale supergravity framework. The model realizes Star…
Cosmology with a Master Coupling in Flipped SU(5) U(1): The Universe
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +2
We propose a complete cosmological scenario based on a flipped SU(5) U(1) GUT model that incorporates Starobinsky-like inflation, taking the subsequent cosmological evolut…
Messengers from the Early Universe: Cosmic Neutrinos and Other Light Relics
Daniel Green, Mustafa A. Amin, Joel Meyers +136
The hot dense environment of the early universe is known to have produced large numbers of baryons, photons, and neutrinos. These extreme conditions may have also produced other lo…
Stochastic Particle Production in a de Sitter Background
Marcos A. G. Garcia, Mustafa A. Amin, Scott G. Carlsten +1
We explore non-adiabatic particle production in a de Sitter universe for a scalar spectator field, by allowing the effective mass of this field and the cosmic time interva…
