Measurement of the b b fraction in hadronic Z decays
Using isolated leptons reconstructed in the Mark II detector to tag {ital b{bar b}} events, we measure the fraction of {ital b{bar b}} events in hadronic {ital Z}{sup 0} decays to be 0.23{sub {minus}0.09}{sup +0.11}, in good agreement with the standard-model prediction of 0.22. We find {Gamma}({ital...

to tag {ital b{bar b}} events, we measure the fraction of {ital b{bar b}} events in hadronic {ital Z}{sup 0} decays to be 0.23{sub {minus}0.09}{sup +0.11}, in good agreement with the standard-model prediction of 0.22. We find {Gamma}({ital Z}{r arrow}{ital b{bar b}})=0.43{sup +0.21}{sub {minus}0.17} GeV.</abstract><cop>United States</cop><doi>10.1103/PhysRevLett.64.1211</doi></addata></record> |
