A study of the $Z$ production cross-section in $pp$ collisions at $\sqrt{s}=7$ TeV using tau final states

The LHCb collaboration, R. Aaij, C. Abellan Beteta +621

A measurement of the inclusive $Z\to \tau \tau$ cross-section in $pp$ collisions at $\sqrt{s}=7$ TeV is presented based on a dataset of 1.0 fb${}^{-1}$ collected by the LHCb detector. Ca…
