Detailed Description

An observable class for the left-right asymmetry in \(e^+e^-\to Z\to \ell^+ \ell^-\) at the \(Z\) pole.

Author
HEPfit Collaboration

This class is used to compute the left-right asymmetry for an \(e^+e^-\to Z\to \ell^+ \ell^-\) process at the \(Z\) pole, where \(\ell\) denotes a charged lepton, and lepton-flavour universality is assumed.
