Single W and Z boson production at the LHC are interesting processes for
many reasons, but in particular since they play a key role in a precise
measurement of the W boson mass. In this talk I will discuss our recent
calculation of mixed QCD-electroweak corrections to these processes. New
aspects of this calculation include the development of a suitable
subtraction scheme to handle infrared singularities in real emissions
and the calculation of the two-loop on-shell form factor for W bosons.
