Abstract

We report evidence for beauty particle production through the observation of dimuon events from proton-antiproton collisions at energies of s=546 GeV and s=630 GeV at the CERN collider. Our data indicate that semi-leptonic decays of beauty particles are the dominant source of pairs of high-p_T muons. The beauty flavour creation (gg or qq→bb) cross-section needed to explain the dimuon rate is σ{pp→bb+X; p^b_T>5 GeV/c, |η|<2.0}=(1.1±0.1±0.4) μb, which is in good agreement with QCD calculations. We also observe clear signals for γ→μ⁺μ^- (hidden beauty) and high-p_TJ/Ψ→μ⁺μ^-, well above the backgraound of continuum muon pairs from the Drell-Yan mechanism.
