jB-meson decays to final states consisting of a D° or D* £ and one or two charged pions have been observed. The charged-B mass is 5270.8± 2.3 ±2.0 MeV and the neutral-E mass is 5274.2±1.9±2.0 MeV. PACS numbers: 14.40.Jz, 13.25.+m, 13.65. + iThe upsiion states 1 are interpreted as q-q resonances of a new quark, the b quark. The first three resonances are narrow, 2 ' 3 implying bound b flavor and a suppressed strong decay. The large width of the T(4S) resonance discovered at the e + e~ storage ring CESR 4 (Cornell Electron Storage Ring) and the observation that the decay products from the T(4S) include high-momentum leptons 5 imply that the T(4S) decays strongly into BB meson pairs, which then decay weakly. Until now, however, the b-flavored mesons themselves had not been found. Here we report that
