Three narrow resonances have been observed in e/sup +/e/sup -/ annihilation into hadrons at total energies between 9.4 and 10.4 GeV. Measurements of mass spacings and ratios of lepton pair widths support the interpretation of these ''UPSILON'' states

A unique part of the CLEO Detector at CESR is the pressurized wire proportional chamber system for particle identification using measurements of ionization loss (dE/dx) in gaseous argon. Each particle traverses the ~ 80 cm thick detector and leaves 1

A study of ${\ensuremath{\pi}}^{\ensuremath{-}}d$ interactions at 13.2 GeV/c has been performed using the SLAC 2-m streamer chamber with a forward-proton trigger/spectrometer. In this paper, we discuss baryon-antibaryon final states where a forward p

An enhancement in the inclusive cross section for single muons produced in e/sup +/e/sup -/ annihilations at the UPSILON(4S) is observed, confirming the interpretation that a new bare flavor (B mesons) is produced at the UPSILON(4S). A branching rati

An enhancement has been observed in the inclusive cross section for direct single electrons produced in e/sup +/e/sup -/ annihilation at the UPSILON(4S). This is interpreted as evidence for a new weakly decaying particle, the B meson. A branching rat
