| Publication Abstract: | Within the framework of transverse-momentum-dependent factorization, we investigate for the first time the impact of a flavor-dependent intrinsic transverse momentum of quarks on the production of W ± bosons in proton-proton collisions at square root s = 7 TeV. We study the transverse-mass and the lepton transverse-momentum distributions of the W-decay products by means of a template-fit technique and we estimate the shift in the W boson mass induced by different choices of flavor-dependent parameters for the intrinsic quark transverse momentum. We obtain -11 lte Delta MW + lte 4 MeV and -6 lte Delta MW - lte 2 MeV with a statistical uncertainty of ±4 MeV. Our findings call for more detailed investigations of flavor-dependent nonperturbative effects linked to the proton structure at hadron colliders. |
