High order QCD predictions for inclusive production of $W$ bosons in $pp$ collisions at $\sqrt{s}$$=13$ TeV (1512.08290v4)

Published 27 Dec 2015 in hep-ph and hep-ex

Abstract: Predictions of fiducial cross sections, differential cross sections and lepton charge asymmetry are presented for the production of $W{\pm}$ bosons with leptonic decay up to next-to-next-to-leading order (NNLO) in perturbative QCD. Differential cross sections of $W{\pm}$ bosons and W boson lepton charge asymmetry are computed as a function of lepton pseudorapidity for a defined fiducial region in $pp$ collisions at $\sqrt{s}=13$ TeV. Numerical results of fiducial $W{\pm}$ cross section predictions are presented with the latest modern PDF models at next-to-leading order (NLO) and NNLO. It is found that the CT14 and NNPDF 3.0 predictions with NNLO QCD corrections are about 4$\%$ higher than the NLO CT14 and NNPDF 3.0 predictions while MMHT 2014 predictions with NLO QCD corrections are smaller than its NNLO QCD predictions by approximately 6$\%$. In addition, the NNLO QCD corrections reduce the scale variation uncertainty on the cross section by a factor of 3.5. The prediction of central values and considered uncertainties are obtained using FEWZ 3.1 program.
