$Z$ and $W$ Physics with Tau-Leptons at the LHC

Measurements of the $Z \to \tau \tau$ and $W \to \tau \nu_{\tau}$ cross-sections in pp collisions at $\sqrt{s}=7 \textrm{TeV}$ the LHC with data taken at are reported for the ATLAS, CMS, and LHCb experiments. Additionally, the polarization of τ-leptons produced from $W \to \tau \nu_{\tau}$ events, as measured by ATLAS, is presented. All results are found to agree with the Standard Model.
