Detailed Description

An observable class for the \(\tau\) polarization in \(e^+e^-\to Z\to \tau^+\tau^-\) at the \(Z\) pole.

Author
HEPfit Collaboration

This class is used to compute the \(\tau\) polarization in the \(e^+e^-\to Z\to \tau^+\tau^-\) process at the \(Z\) pole,

\[ P_\tau^{\mathrm{pol}}=\mathrm{A}_\tau\,. \]
