W-boson production in TMD factorization

Understand

At hadron colliders, the differential cross section for $W$ production can be factorized and it is sensitive transverse momentum dependent distributions (TMD) for low boson transverse momentum.

• While, often, the corresponding non-perturbative QCD contributions are extrapolated from $Z$ boson production, here we use an existing extraction (based on the code Artemide) of TMD which includes data coming from Drell-Yan and semi-inclusive deep inelastic scattering, to provide checks and predictions for the $W$ case.
• Including fiducial cuts with different configurations and kinematical power corrections, we consider transverse momentum dependent cross sections within several intervals of the vector boson transverse mass.
• We perform the same study for the $p_T^{W^-}/p_T^{W^+}$ and $p_T^Z/p_T^W$ distributions.
