Description
The first measurement of the Z -> tautau cross-section in the mu-taujet, e-taujet, e-mu and mu-mu final states is presented. The data collected in 2010 with the CMS detector from proton-proton collisions at √s = 7 TeV are used, corresponding to an integrated luminosity of about 36 pb-1. The cross section has been measured to be in good agreement with the next-to-next-to- leading order QCD prediction.The production of Z bosons decaying into tau pairs serves as an important benchmark for tau reconstruction and constitutes a reference Standard Model process for searches at the LHC, like the MSSM H -> tautau.
