Abstract

Three narrow resonances have been observed in e+e- annihilation into hadrons at total energies between 9.4 and 10.4 GeV. Measurements of mass spacing and ratios of lepton pair widths support the interpretation of these " " states as the lowest triplet-S levels of the bb̄ quark-antiquark system. © 1980 The American Physical Society.
