$Z \to \tau\tau$ and $W \to \tau\nu_\tau$ Cross-Sections at the LHC
  Measurements of the $Z \to \tau\tau$ and $W \to \tau\nu_\tau$ cross-sections at the LHC with data taken at $\sqrt{s} = 7$ TeV are reported for the ATLAS, CMS, and LHCb experiments. All results are found to agree with the Standard Model.
