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 ⁎-distribution and compare our results with the ultra-precise experimental data. We extract the free parameters in each parameterization with a 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.

Abstract
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 ⁎-distribution and compare our results with the ultra-precise experimental data. We extract the free parameters in each parameterization with a 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.File in questo prodotto:
