Description

Using CLEO data, we report on the confirmation of the ηb(1S0) ground state of bottomonium in the radiative decay Υ(3S)→γηb We determine its mass to be M(ηb) = 9391.8±6.6±2.1 MeV, which corresponds to the hyperfine splitting ΔMhf(1S) = 68.5±6.6±2.0 MeV, and the branching fraction B(Υ(3S)γηb) = (7.1±1.8±1.1)x10-4. These results agree with those previously reported by BaBar.
