A Study of $b\overline{b}$ Production in $e^+e^-$ Collisions at $\sqrt(s) = 130-207 GeV$ (2009)

Abstract
Measurements are presented of R_b, the ratio of the b bbar cross-section to the q qbar cross-section in e+e- collisions, and the forward-backward asymmetry A^b_FB 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.
