A study of b anti-b production in e e- collisions at sqrts=130 -207 GeV

Abstract

Measurements are presented of R b, the ratio of the b anti-b cross-section to the q anti-q cross-section in e e- collisions, and the forward-backward asymmetry A FBb at twelve energy points in the range $\sqrt{s}=130$ -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.
