Enhancement of the Dark Matter Abundance Before Reheating: Applications to Gravitino Dark Matter
Marcos A. G. Garcia, Yann Mambrini, Keith A. Olive +1
In the first stages of inflationary reheating, the temperature of the radiation produced by inflaton decays is typically higher than the commonly defined reheating temperature $T_{…

Multifield Stochastic Particle Production: Beyond a Maximum Entropy Ansatz
Mustafa A. Amin, Marcos A. G. Garcia, Hong-Yi Xie +1
We explore non-adiabatic particle production for coupled scalar fields in a time-dependent background with stochastically varying effective masses, cross-couplings and…

Starobinsky-like Inflation, Supercosmology and Neutrino Masses in No-Scale Flipped SU(5)
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +2
We embed a flipped GUT model in a no-scale supergravity framework, and discuss its predictions for cosmic microwave background observables, which ar…
