Description

The 26.7 km long Large Electron Positron collider (LEP) was operated at CERN between 1989 and 2000. The most precise measurements of the Z boson mass and width were made possible thanks to high precision energy calibration of the LEP beams with resonant depolarization. Transversely polarized beams had to be established at LEP to achieve this goal, providing a rich legacy of data on polarized beams at beam energies around 45 GeV. The beam dynamics simulation package Xsuite was recently enhanced to track polarized beams and to evaluate the equilibrium polarization of beams and related quantities. Xsuite code benchmarking with LEP results on transverse polarization and resonant depolarization will be presented in this contribution.
