The proposed LDMX experiment would provide roughly a meter-long region of instrumented
tracking and calorimetry that acts as a beam stop for multi-GeV electrons in which each …

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 …

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 …

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

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 …

In the presence of self-interactions, the post-inflationary evolution of the inflaton field is
driven into the non-linear regime by the resonant growth of its fluctuations. The once …

We consider the effects of fragmentation on the post-inflationary epoch of reheating. In
simple single field models of inflation, an inflaton condensate undergoes an oscillatory …

Recent BICEP/Keck data on the cosmic microwave background, in combination with
previous WMAP and Planck data, impose strong new constraints on the tilt in the scalar …

Gravitational particle production is a minimal contribution to reheating the Universe after the
end of inflation. To study this production channel, two different approaches have commonly …
