摘要: Limits are set on B/sup 0/B-bar/sup 0/ mixing by use of dilepton events from UPSILON(4S) decay. On the assumption that charged- and neutral-B semileptonic branching ratios equal 41% B mesons neutral, a 90%-confidence-level upper limit 24% is mixing. also given for ratio lifetimes neutral charged mesons. The limits 0.44
