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…
Reheating and Dark Matter Production
Marcos A. G. Garcia
A concise summary of out-of-equilibrium dark matter production during post-inflationary reheating is presented. We show that the dark matter relic abundance is in general sensitive…
How warm are non-thermal relics? Lyman- bounds on out-of-equilibrium dark matter
Guillermo Ballesteros, Marcos A. G. Garcia, Mathias Pierre
We investigate the power spectrum of Non-Cold Dark Matter (NCDM) produced in a state out of thermal equilibrium. We consider dark matter production from the decay of scalar condens…
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…
The case for decaying spin-3/2 dark matter
Marcos A. G. Garcia, Yann Mambrini, Keith A. Olive +1
We couple a sterile neutrino sector to a spin-3/2 particle and show that with a Planck reduced coupling, we can obtain a sufficiently long lifetime making the spin-3/2 particle a g…
Reheating and Post-inflationary Production of Dark Matter
Marcos A. G. Garcia, Kunio Kaneta, Yann Mambrini +1
We perform a systematic analysis of dark matter production during post-inflationary reheating. Following the period of exponential expansion, the inflaton begins a period of damped…
Proton Decay: Flipped vs Unflipped SU(5)
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +2
We analyze nucleon decay modes in a no-scale supersymmetric flipped SU(5) GUT model, and contrast them with the predictions for proton decays via dimension-6 operators in a standar…
Curvature Perturbations From Stochastic Particle Production During Inflation
Marcos A. G. Garcia, Mustafa A. Amin, Daniel Green
We calculate the curvature power spectrum sourced by spectator fields that are excited repeatedly and non-adiabatically during inflation. In the absence of detailed information of…
