摘要Proof of transverse-momentum-dependent factorization for hadron-hadron collisions is given in this paper. We focus on processes without detected soft final hadrons or detected final hadrons that are collinear to the initial hadrons. This contradicts the widely accepted viewpoint that transverse-momentum-dependent factorization does not hold in such processes even in the generalized sense. The key point is that singular points of the type l(+) = 0 can be absorbed into the Wilson lines of soft gluons, where l is collinear to the plus direction. Thus, one should subtract such singular points from the collinear region of l. After such subtraction, one can make use of the Ward identity to absorb the effects of scalar-polarized collinear gluons into Wilson lines.
