We report the first large-acceptance measurement of the beam–spin asymmetry for deuteron photodisintegration (γ→ d→ p n) in the photon energy range 420< E γ< 620 MeV. The measurement provides important new constraints on the mechanisms of photodisintegration above the Δ resonance and on the photocoupling of the recently discovered d⁎(2380) hexaquark.
