Popis: | A novel approach to detect light dark matter through the observation of a single photon in the decay of Positronium (Ps) is proposed. Branching ratio calculations indicate that light dark matter coupling to the Standard Model through a novel dark vector boson in the mass range mA′ = 10–500 keV with strength ϵ = 2 × 10−5–10−8 is well above the previously computed Standard Model background decay Ps → γνν and could be sensitive to observation. |
