A recent measurement by the D0 Collaboration, of the charge asymmetry of muons in $W\rightarrow\mu\nu$ events is discussed. Using 4.9 fb$^{-1}$ of data collected by the D0 detector, the muon charge asymmetry, $A(\eta)$, where $\eta$ is the…
Measurements of the $W$ boson mass are planned by the ATLAS and CMS experiments, but for the time being, these may be unable to compete with the current world average precision of 15~MeV, due to uncertainties in the PDFs. We discuss the…
