Abstract
The cross section for b (b) over bar production in 800 GeV/c pN interaction s 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 th e b and the (b) over bar decay semimuonically or a B decays into a J/psi fo llowed by J/psi --> mu(+)mu(-).
