Abstract

The cross section for $b\overline{b}$ production in $800\mathrm{GeV}/c$ $\mathrm{pN}$ interactions has been measured in Fermilab experiment E771 to be ${43}_{\ensuremath{-}17}^{+27}(\mathrm{stat}{)}_{\ensuremath{-}7}^{+7}(\mathrm{syst})\mathrm{nb}$ per nucleon from the observation of events in which both the $b$ and the $\overline{b}$ decay semimuonically or a $B$ decays into a $J/\ensuremath{\psi}$ followed by $J/\ensuremath{\psi}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$.
