Creation of spin-3/2 dark matter via cosmological gravitational particle production
Edward W. Kolb, Andrew J. Long, Evan McDonough +1
We study the cosmological gravitational particle production (CGPP) of spin-3/2 particles during and after cosmic inflation, and map the parameter space that can realize the observe…
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…
Superheavy Dark Matter from the String Theory Axiverse
Siyang Ling, Andrew J. Long, Evan McDonough +1
We propose heavy axions as a natural superheavy dark matter candidate in string theory, with the relic density of dark matter originating in quantum fluctuations during cosmic infl…
Wave Interference in Self-Interacting Fuzzy Dark Matter
Christian Capanelli, Wayne Hu, Evan McDonough
In the Fuzzy Dark Matter (FDM) scenario, the dark matter is composed of an ultra-light scalar field with coherence length and wave interference on astrophysical scales. Scalar fiel…
