$Z \to \tau\tau$ and $W \to \tau\nu_\tau$ Cross-Sections at the LHC

TL;DR

This paper reports measurements of Z and W boson decay cross-sections to tau leptons at 7 TeV LHC, confirming consistency with the Standard Model across multiple experiments.

Contribution

First comprehensive measurements of Z to tau tau and W to tau nu cross-sections at 7 TeV LHC by ATLAS, CMS, and LHCb, validating Standard Model predictions.

Findings

Results agree with Standard Model expectations.

Measurements across three experiments are consistent.

Provides baseline for future tau lepton studies.

Abstract

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.
