ENERGY SCAN FOR NARROW STATES IN E+E-ANNIHILATION AT CM ENERGIES BETWEEN 29.90 AND 31.46 GEV
A fine energy scan has been performed to search for narrow states in e+e- annihilation at c.m. energies between 29.90 and 31.46 GeV. No such state has been observed. The 90% confidence upper limit on the leptonic decay width times the hadronic decay branching ratio is ΓeeBh<1.6 keV. © 1979.
