Abstract: A measurement of inclusive Z to τ+τ− production in pp collisions is presented, in the final states μ+hadrons, e+hadrons, e+μ, and μ+μ. The data sample corresponds to an integrated luminosity of 36 inverse picobarns collected with the CMS detector at the LHC. The measured cross section is σ(pp→Z)B(Z→τ+τ−) = 1.00 ± 0.05 (stat.) ± 0.08 (syst.) ± 0.04 (lumi.) nb, which is in good agreement with the next-to-next-to-leading order QCD prediction and with previous measurements in the Z→e+e− and μ+μ− channels. The reconstruction efficiency for hadronic tau decays is determined with a precision of 7%. | ||
