Detailed Description

An observable class for \(R_{uc}=(\Gamma(Z\to\ u\bar{u})+\Gamma(Z\to\ c\bar{c}))/2\Gamma(Z\to {\rm hadrons})\).

This class is used to compute the ratio of the \(Z\to u\bar{u} + Z\to c\bar{c}\) width to the \(Z\)-boson hadronic width:

\[ R_{uc} = \frac{\Gamma_u+\Gamma_c}{\Gamma_h}\,. \]
