TL;DR: In this article, the OPAL experiment at LEP at centre-of-mass energies between 182 and 209 GeV was used to measure R b, the ratio of the b b ¯ cross-section to the q q ¯ crosssection in e + e − collisions, and the mean ratio of eight measurements reported here to the Standard Model prediction is 1.055 ± 0.031 − 0.037, where the first error is statistical and the second systematic.
