Nonperturbative Uncertainties on the Transverse Momentum Distribution of Electroweak Bosons and on the Determination of the Boson Mass at the LHC

Figure 2

From top to bottom: the decomposition in flavour channels of the cross section for , , production differential with respect to the transverse momentum of the produced electroweak boson , . The rapidity and the collinear momentum fractions have been integrated over the kinematically allowed ranges. The cross section is calculated by means of CuTe [12] at LHC  TeV. The nonperturbative correction is implemented as a flavour-independent Gaussian smearing, governed by the parameter (see [12] and the Appendix). The channels add to one.
