A study of the role of the PDF uncertainty on the LHC W-boson mass measurement
Abstract
The determination of the W-boson mass through an analysis of the decay charged-lepton transverse momentum distribution has a sizable uncertainty due to the imperfect knowledge of the relevant parton distribution functions (PDFs). In this work, a quantitative assessment of the W-boson mass uncertainty at the LHC resulting from the PDF uncertainty is examined. We use the CT14 NNLO PDFs with a NNLL + NNLO calculation (ResBos) to simulate the W-boson production and decay kinematics. The uncertainty of the W-boson mass determination is then determined as a function of the boson and lepton kinematics. For W+ production using $$P^{W}_{T}$$ < 15 GeV and 35 < $$P^{l}_{T}$$ (GeV) < 45, PDF uncertainties lead (at the 68% CL) to a mass uncertainty for the $$M^{+}_{W}$$ of $$^{+16.0}_{-17.5}$$ MeV, $$^{+13.9}_{-14.8}$$ MeV, and $$^{+12.2}_{-19.2}$$ MeV, are determined at 7 TeV, 8 TeV and 13 TeV, respectively. The uncertainties of $$M^{-}_{W}$$ for the same cuts are found to be $$^{+15.9}_{-15.6}$$ MeV, $$^{+15.0}_{-12.7}$$ MeV and $$^{+14.8}_{-15.3}$$ MeV at 7 TeV, 8 TeV and 13 TeV, respectively.
