Abstract

In hadronic decays of Z bosons recorded with the OPAL detector at LEP, events containing b quarks were selected using the long lifetime of b flavoured hadrons. Comparing the 3-jet rate in b events with that in d,u,s and c quark events, a significant difference was observed. Using script O sign(α2 S) calculations for massive quarks, this difference was used to determine the b quark mass in the MS renormalisation scheme at the scale of the Z boson mass. By combining the results from seven different jet finders the running b quark mass was determined to be m̄b(mz) = (2.67 ± 0.03(stat.)+0.29 -0.37(syst.)±0.19(theo.)) GeV. Evolving this value to the b quark mass scale itself yields m̄b(m̄b) = (3.95+0.52 -0.6) GeV, consistent with results obtained at the b quark production threshold. This determination confirms the QCD expectation of a scale dependent quark mass. A constant mass is ruled out by 3.9 standard deviations.

N2 - In hadronic decays of Z bosons recorded with the OPAL detector at LEP, events containing b quarks were selected using the long lifetime of b flavoured hadrons. Comparing the 3-jet rate in b events with that in d,u,s and c quark events, a significant difference was observed. Using script O sign(α2 S) calculations for massive quarks, this difference was used to determine the b quark mass in the MS renormalisation scheme at the scale of the Z boson mass. By combining the results from seven different jet finders the running b quark mass was determined to be m̄b(mz) = (2.67 ± 0.03(stat.)+0.29 -0.37(syst.)±0.19(theo.)) GeV. Evolving this value to the b quark mass scale itself yields m̄b(m̄b) = (3.95+0.52 -0.6) GeV, consistent with results obtained at the b quark production threshold. This determination confirms the QCD expectation of a scale dependent quark mass. A constant mass is ruled out by 3.9 standard deviations.
