Z0-boson production at low transverse momentum offers a unique opportunity to explore the non-perturbative Sudakov factor. In this paper, we employ three parameterizations of the non-perturbative Sudakov factor to calculate the ϕ⁎-distribution and compare our results with the ultra-precise experimental data. We extract the free parameters in each parameterization with a χ2 analysis. The parton-momentum-fraction dependence of these free parameters is also studied by comparing the values extracted at different collision energies and different rapidity ranges.
