Inflaton Production of Scalar Dark Matter through Fluctuations and Scattering
Gongjun Choi, Marcos A. G. Garcia, Wenqi Ke +3
We study the effects on particle production of a Planck-suppressed coupling between the inflaton and a scalar dark matter candidate, . In the absence of this coupling, the domin…

Inflaton decay in No-Scale Supergravity and Starobinsky-like models
Yohei Ema, Marcos A. G. Garcia, Wenqi Ke +2
We consider the decay of the inflaton in Starobinsky-like models arising from either an theory of gravity or no-scale supergravity models. If Standard Model matter is…
