It is commonly assumed that the energy density of the Universe was dominated by radiation
between reheating after inflation and the onset of matter domination 54,000 years later …

Increasingly stringent limits from LHC searches for new physics, coupled with lack of
convincing signals of weakly interacting massive particle (WIMP) in dark matter searches …

We perform a systematic analysis of dark matter production during postinflationary
reheating. Following the period of exponential expansion, the inflaton begins a period of …

A bstract If even a relatively small number of black holes were created in the early universe,
they will constitute an increasingly large fraction of the total energy density as space …

We consider the direct s-channel gravitational production of dark matter during the reheating
process. Independent of the identity of the dark matter candidate or its nongravitational …

We analyze in detail the perturbative decay of the inflaton oscillating about a generic form of
its potential V (ϕ)= ϕ k, taking into account the effects of non-instantaneous reheating. We …

The study of cosmic phase transitions are of central interest in modern cosmology. In the
standard model of cosmology the Universe begins in a very hot state, right after at the end of …

Current upper bounds on the neutron electric dipole moment constrain the physically
observable quantum chromodynamic (QCD) vacuum angle| θ|≲ 10− 11. Since QCD …

We investigate the effects of producing dark matter by the Hawking evaporation of primordial
black holes (PBHs) in scenarios that may have a second well-motivated dark matter …

Reheating is an important part of inflationary cosmology. It describes the production of
Standard Model particles after the phase of accelerated expansion. We review the reheating …
