AbstractThe DØ experiment at Fermilab has determined the B meson-neutral anti-B meson mixing probability X using dimuon events produced in proton anti-proton collisions at √s = 1.8 TeV. Using a sample of 183 dimuon events, we have determined the time and flavor averaged mixing probability X to be 0.09 ± 0.04(stat) ± 0.03(sys) in agreement with the present world average for this parameter.
