Dark Nuclei I: Cosmology and Indirect Detection [PDF]

open access: yesPhys. Rev. D 90, 115013 (2014), 2014
In a companion paper (to be presented), lattice field theory methods are used to show that in two-color, two-flavor QCD there are stable nuclear states in the spectrum. As a commonly studied theory of composite dark matter, this motivates the consideration of possible nuclear physics in this and other composite dark sectors.

The Darkness of Dark Matter and Dark Energy

open access: yesInternational Journal of Engineering and Applied Sciences (IJEAS), 2018
The visible universemdashincluding Earth, the sun, other stars, and galaxiesmdashis made of protons, neutrons, and electrons bundled together into atoms. Perhaps one of the most surprising discoveries of the 20th century was that this ordinary, or baryonic, matter makes up less than 5 percent of the mass of the universe.
