Cosmic quarkonium: A probe of dark matter
Abstract
If our galactic halo is composed of heavy (several gigaelectron- volts), weakly interacting particles, pair annihilation into a heavy-quark-antiquark bound state plus a monochromatic photon can produce potentially observable sharp peaks in the diffuse cosmic-γ-ray background.
