Gravitational production of super-Hubble-mass particles: an analytic approach
Daniel J. H. Chung, Edward W. Kolb, Andrew J. Long
Through a mechanism similar to perturbative particle scattering, particles of mass larger than the Hubble expansion rate during inflation can be gravitationa…
Dark Quark Nuggets
Yang Bai, Andrew J. Long, Sida Lu
"Dark quark nuggets", a lump of dark quark matter, can be produced in the early universe for a wide range of confining gauge theories and serve as a macroscopic dark matter candida…
WIMPflation
Dan Hooper, Gordan Krnjaic, Andrew J. Long +1
We propose a class of models in which a stable inflaton is produced as a thermal relic in the early universe and constitutes the dark matter. We show that inflaton annihilations ca…
Six Flavor Quark Matter
Yang Bai, Andrew J. Long
Macroscopic nuggets of quark matter were proposed several decades ago as a candidate for dark matter. The formation of these objects in the early universe requires the QCD phase tr…
Cosmological Aspects of the Clockwork Axion
Andrew J. Long
The clockwork axion refers to a family of aligned multi-axion models that lead to an exponential hierarchy between the scale of Peccei-Quinn symmetry breaking and the scale of the…
