Abstract
The CUSB detector at the Cornell Electron Storage Ring was used to measure the inclusive photon spectrum at the ′′′(10.55). In ∼5000 ′′′ events we see no obvious ∼50-MeV photon signal from B*→B+γ decays and obtain an upper limit on the branching ratio for ′′′→BB* of ∼10% with a 90% confidence level. From the lack of a photon signal and the observed width of the ′′′, we deduce limits on the B-meson mass of [M(′′′)2-25 MeV]
