Phys. Rev. Lett. 82, 41–44 (1999)Measurement of the bb̅ Cross Section in 800GeV/c Proton-Silicon InteractionsReceived 7 July 1997; revised 1 September 1998; published in the issue dated 4 January 1999 The cross section for bb̅ production in 800GeV/c pN interactions has been measured in Fermilab experiment E771 to be 43-17+27(stat)-7+7(syst)nb per nucleon from the observation of events in which both the b and the b̅ decay semimuonically or a B decays into a J/ψ followed by J/ψ→μ+μ-. © 1999 The American Physical Society URL:
