Description
This analysis note is meant to be a telegraphic transcript of an ongoing analysis aimed at assessing the precision that can be reached at FCC-ee for the partial-width measurement of $Z \to c \bar{c}$. Intermediate results are also presented for the $c$-quark forward-backward asymmetry. Furthermore, it highlights the idea of measuring $R_s$ and $A_\text{FB}^s$ with exclusively reconstructed strange hadrons.
