Cosmological gravitational particle production of massive spin-2 particles
Edward W. Kolb, Siyang Ling, Andrew J. Long +1
The phenomenon of cosmological gravitational particle production (CGPP) is expected to occur during the period of inflation and the transition into a hot big bang cosmology. Partic…
Completely Dark Matter from Rapid-Turn Multifield Inflation
Edward W. Kolb, Andrew J. Long, Evan McDonough +1
We study cosmological gravitational particle production as applied to "rapid-turn" models of inflation involving two scalar fields. We are interested in the production of massive s…
Quantum interference in gravitational particle production
Edward Basso, Daniel J. H. Chung, Edward W. Kolb +1
Previous numerical investigations of gravitational particle production during the coherent oscillation period of inflation displayed unexplained fluctuations in the spectral densit…
Snowmass2021 Cosmic Frontier White Paper: Ultraheavy particle dark matter
Daniel Carney, Nirmal Raj, Yang Bai +25
We outline the unique opportunities and challenges in the search for "ultraheavy" dark matter candidates with masses between roughly and the Planck scale $m_{\rm pl}…
The Gravitino Swampland Conjecture
Edward W. Kolb, Andrew J. Long, Evan McDonough
We extend the swampland from effective field theories (EFTs) inconsistent with quantum gravity to EFTs inconsistent with quantum supergravity. This enlarges the swampland to includ…
Catastrophic Production of Slow Gravitinos
Edward W. Kolb, Andrew J. Long, Evan McDonough
We study gravitational particle production of the massive spin- Rarita-Schwinger field, and its close relative, the gravitino, in FRW cosmological spacetimes. For masses light…
