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

Figure 3

In these figures the ratio is plotted for the three different electroweak bosons (, , , respectively), with a single set of flavour-independent (f.i.) nonperturbative parameters in the transverse part of the TMD PDFs and 50 different flavour-dependent (f.d.) sets of the same parameters. The analysis has been performed at NLL [11, 13]. The values of the nonperturbative parameters have been chosen from the results in [14, 15].
