Electroweak Heavy-flavor update summary for summer-01 ===================================================== A common update: The LEP EWWG has updated some standard input parameters: b->tau->l: 0.419+/-0.055% (was 0.452+/-0.74%) b->J/Psi->l: 0.072+/-0.006% (was 0.07+/-0.02%) g->bbbar: 0.00254+/-0.00051 (was 0.00251+/-0.00063) g->ccbar: 0.0296+/-0.0038 (was 0.0319+/-0.0046) These are incoperated into all measurements which are sensitive to them. Rb: 1) Nicolo rerun analysis with new tracking resolution corrections. 2) Re-estimated g->QQ correction/systematics. 3) Re-estimated running b quark mass event selection bias based on additional infor from Sean's generator tests. Rc: 1) New tracking resolution 2) Full standard systematic list. Ab,Ac lepton: 1) Corrected combination bugs in May. 2) rescaled results for new g->QQ. Ab,Ac K+Vtx: 1) Ab analysis became Vtx-charge only. 2) Refined QCD correction. Ab jet-charge: No change from Winter-01 Ac D*,D: No change from winter-01 (published PRD).
