abstract = {The parton branching method is crucial for Monte Carlo
generators, which are essential for high-energy physics
predictions. We examine the impact of soft gluons on
inclusive collinear and Transverse Momentum Dependent (TMD)
parton densities. By applying the Parton-Branching (PB)
method, we identify the non-perturbative Sudakov form factor
with the integration range $z \to 1$, which is often
neglected in collinear parton shower approaches. The
significance of soft gluons is demonstrated through the
transverse momentum spectrum of Drell-Yan lepton pairs,
resulting in an intrinsic-$k_t$ distribution width that
remains independent of $\sqrt(s)$, contrary to observations
in collinear parton shower approaches. This behavior is
attributed to the non-perturbative Sudakov form factor.},
