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…
Higher Spin Dark Matter
Stephon Alexander, Leah Jenks, Evan McDonough
Little is known about dark matter beyond the fact that it does not interact with the standard model or itself, or else does so incredibly weakly. A natural candidate, given the his…
Strongly-Interacting Ultralight Millicharged Particles
Stephon Alexander, Evan McDonough, David N. Spergel
We consider the implications of an ultra-light fermionic dark matter candidate that carries baryon number. This naturally arises if dark matter has a small charge under standard mo…
Constraining Early Dark Energy with Large-Scale Structure
Mikhail M. Ivanov, Evan McDonough, J. Colin Hill +4
An axion-like field comprising of the energy density of the universe near matter-radiation equality is a candidate to resolve the Hubble tension; this is the "early dar…
The Cosmological Heavy Ion Collider: Fast Thermalization after Cosmic Inflation
Evan McDonough
Heavy-ion colliders have revealed the process of "fast thermalization". This experimental breakthrough has led to new theoretical tools to study the thermalization process at both…
