The cross section for bb production in 800 GeV/c pN interactions has been measured in Fermilab experiment E771 to be 43+27− 17(stat)+7-7(syst) nb per nucleon from the observation of events in which both the b and the b decay semimuonically or a B decays into a J/ψ followed by J/ψ → ε+ε−. © 1999 The American Physical Society.

Abstract
The cross section for bb production in 800 GeV/c pN interactions has been measured in Fermilab experiment E771 to be 43+27− 17(stat)+7-7(syst) nb per nucleon from the observation of events in which both the b and the b decay semimuonically or a B decays into a J/ψ followed by J/ψ → ε+ε−. © 1999 The American Physical Society.File in questo prodotto:
