Kaluza-Klein Towers in the Early Universe: Phase Transitions, Relic Abundances, and Applications to Axion Cosmology
Keith R. Dienes, Jeff Kost, Brooks Thomas
We study the early-universe cosmology of a Kaluza-Klein (KK) tower of scalar fields in the presence of a mass-generating phase transition, focusing on the time-development of the t…
Dynamical Dark Matter from Strongly-Coupled Dark Sectors
Keith R. Dienes, Fei Huang, Shufang Su +1
Dynamical Dark Matter (DDM) is an alternative framework for dark-matter physics in which the dark sector comprises a vast ensemble of particle species whose decay widths are balanc…
Boxes, Boosts, and Energy Duality: Understanding the Galactic-Center Gamma-Ray Excess through Dynamical Dark Matter
Kimberly K. Boddy, Keith R. Dienes, Doojin Kim +3
Many models currently exist which attempt to interpret the excess of gamma rays emanating from the Galactic Center in terms of annihilating or decaying dark matter. These models ty…
Lines and Boxes: Unmasking Dynamical Dark Matter through Correlations in the MeV Gamma-Ray Spectrum
Kimberly K. Boddy, Keith R. Dienes, Doojin Kim +3
Identifying signatures of dark matter at indirect-detection experiments is generally more challenging for scenarios involving non-minimal dark sectors such as Dynamical Dark Matter…
Randomness in the Dark Sector: Emergent Mass Spectra and Dynamical Dark Matter Ensembles
Keith R. Dienes, Jacob Fennick, Jason Kumar +1
In general, non-minimal models of the dark sector such as Dynamical Dark Matter posit the existence of an ensemble of individual dark components with differing masses, cosmological…
