Measurements are presented of R b , the ratio of the cross-section to the cross-section in e + e − collisions, and the forward-backward asymmetry A FB b at twelve energy points in the range –207 GeV. These results are found to be consistent with the Standard Model expectations. The measurements are used to set limits on new physics scenarios involving contact interactions.
