A Measurement of the b anti-b cross-section in 800-GeV/c proton silicon interactions
1999
The cross section for b{bar b} production in 800 GeV/c pN interactions has been measured in Fermilab experiment E771 to be 43{sup +27}{sub {minus}17}(stat){sup +7}{sub {minus}7}(syst) nb per nucleon from the observation of events in which both the b and the {bar b} decay semimuonically or a B decays into a J/{psi} followed by J/{psi}{r_arrow}{mu}{sup +}{mu}{sup {minus}} . {copyright} {ital 1998} {ital The American Physical Society}
