Detailed Description

An observable class for \(R_\nu^0=\sum \Gamma(Z\to \nu \bar{\nu})/\Gamma(Z\to {\rm hadrons})/\).

Author
HEPfit Collaboration

This class is used to compute the ratio of the \(Z\)-boson invisible and hadronic widths:

\[ R_\nu = \sum \Gamma(Z\to \nu \bar{\nu})/\Gamma(Z\to {\rm hadrons})\,, \]

where \(\nu\) denotes a neutrino.
