Higgs Inflation: Particle Factory
Tammi Chowdhury, Leah Jenks, Edward W. Kolb +1
We study cosmological gravitational particle production (CGPP) in Higgs inflation, wherein the inflaton is a scalar field with quartic self-coupling and a nonminimal coupling t…

Gravitational Particle Production of Scalars: Analytic and Numerical Approaches Including Early Reheating
Leah Jenks, Edward W. Kolb, Keyer Thyme
Cosmological gravitational particle production (GPP) is a generic mechanism by which particles are produced during the inflationary epoch. In this work we consider the GPP of massi…

Gravitational Production of Completely Dark Photons with Nonminimal Couplings to Gravity
Christian Capanelli, Leah Jenks, Edward W. Kolb +1
Dark photons are a theorized massive spin-1 particle which can be produced via various mechanisms, including cosmological gravitational particle production (GPP) in the early unive…
