Combination of the LEP II ffbar Results

Preliminary combinations of measurements of the 4 LEP collaborations of the process e+e- -> f\bar f at LEP-II are presented, using data from the full LEP-II data set where available. Cross-sections and forward-backward asymmetry measurements are combined for the full LEP-II data set. Combined differential cross-sections d\sigma/dcos\theta for electron-pairs, muon-pair ant tau-pair final states are presented. Measurements of the production of heavy flavours are combined. The combined results are interpreted in terms of contact interactions and the exchange of Z'bosons and leptoquarks, and within models of low scale gravity in large extra dimensions.
