Description

We propose a scenario in which dark energy and dark matter are described in a unified manner. The ultralight pseudo-Nambu-Goldstone (pNG) boson, Α, naturally explains the observed magnitude of dark energy, while the bosonic supersymmetry partner of the pNG boson, Β, can be a dominant component of dark matter. The decay of Β into a pair of electron and positron may explain the 511 keV γ ray from the Galactic Center. (orig.)
