Measurement of the $$W$$ boson mass with the D0 detector
We give a detailed description of the measurement of the $$W$$ boson mass, $$M_W$$, performed on an integrated luminosity of 4.3 fb$$^{-1}$$, which is based on similar techniques as used for our previous measurement done on an independent data set of 1 fb$$^{-1}$$ of data. The data were collected using the D0 detector at the Fermilab Tevatron Collider. This data set yields $$1.68\times 10^6$$ $$W\rightarrow e\nu$$ candidate events. We measure the mass using the transverse mass, electron transverse momentum, and missing transverse energy distributions. The $$M_W$$ measurements using the transverse mass and the electron transverse momentum distributions are the most precise of these three and are combined to give $$M_W$$ = 80.367 $$\pm$$ 0.013 (stat) $$\pm$$ 0.022 (syst) GeV = 80.367 $$\pm$$ 0.026 GeV. When combined with our earlier measurement on 1 fb$$^{-1}$$ of data, we obtain $$M_W$$ = 80.375 $$\pm$$ 0.023 GeV.
