Search for Production of Invisible Final States in Single-Photon Decays of Gamma(1S)
We search for single-photon decays of the Υ(1S) resonance, Υ→γ+invisible, where the invisible state is either a particle of definite mass, such as a light Higgs boson A[superscript 0], or a pair of dark matter particles, χχ̅ . Both A[superscript 0] and χ are assumed to have zero spin. We tag Υ(1S) d...
