Description
The proposed FCC-ee collider will improve electroweak precision measurements by orders-of-magnitude, producing new measurements and potentially revealing inconsistencies within the Standard Model. In our work, we investigate tau polarization precision measurements in order to project finer uncertainties on fundamental SM parameters, including the weak mixing angle. We perform a realistic Monte Carlo study in the FCC-ee framework on the tau polarization at the center-of-mass energy of 91.2 GeV. Boosted decision trees (BDTs) are applied to optimize the identification of the 1-prong and 3-prong tau decay modes. These are then used to derive measurements of the tau polarization by fitting to analytical energy distributions.
