| Popis: |
We have performed a search for narrow resonances in the center of mass energy range from 29.90 to 31.46 GeV using the e+e− storage ring PETRA at DESY. We present the total cross section for hadron production and an upper limit for resonance production, indicating that no bound state of charge- 2 3 quarks exists in this energy range. |
