These results are preliminary, based on our full 1993-1998 dataset of 550 000 hadronic Z0 decays produced with an average electron polarisation of 73%. The new measurements are of the hadronic branching fractions into heavy quarks (Rb, Rc), the b quark asymmetry (Ab) using jet charge, and the heavy quark asymmetries (Ab and Ac) using vertex charge and kaons.4 pages, 2 figures.
