Phys. Rev. Lett. 53, 2215–2218 (1984)Scalar-Quark Bound-State Interpretation of the ζ(8.3)Received 6 September 1984; published in the issue dated 3 December 1984 We interpret the ζ(8.3 GeV) as the 0++ ground state of a scalar-quark (σσ―) bound system where σ is a color triplet and has electric charge |Q|=1/3. With the use of the quarkonium potential model, the energy of the third (1--) P state is calculated to be within 50 MeV of the ϒ state. If it falls within the machine energy spread (20 MeV at DORIS) of the ϒ, all existing data can be understood. © 1984 The American Physical Society URL:
