Description
The talk presents the feasibility of a novel $b$-hemisphere tagger and its application at the Tera-$Z$ programme at FCC-ee for the measurement of the partial width $R_b$ and the $b$-quark forward-backward asymmetry $A_{\text{FB}}^b$. By exclusively reconstructing $b$-hadrons in the hemispheres, the major source of systematic uncertainties originating from light- and $c$-physics is eliminated. A discussion of the only remaining uncertainties is given and their impact on the measurement is estimated.
