Measuring $$A_\textrm{FB}^b$$ A FB b and $$R_b$$ R b with exclusive b-hadron decays at the FCC-ee
Abstract This paper presents a novel tagging technique to measure the beauty-quark partial decay-width ratio $$R_b$$ R b and its forward–backward asymmetry $$A_{\textrm{FB}}^b$$ A FB b at the FCC-ee, using $$\mathcal {O}(10^{12})$$ O ( 10 12 ) Z-boson decays. The method is based on the exclusive rec...
