Non-perturbative contributions to vector-boson transverse momentum spectra in hadronic collisions

Experimental measurements of Drell-Yan (DY) vector-boson production are available from the Large Hadron Collider (LHC) and from lower-energy collider and fixed-target experiments. In the region of low vector-boson transverse momenta q(T), which is important for the extraction of the W-boson mass at...
