| Özet |
| The first measurement of inclusive Z→ τ+ τ− production in pp collisions at the LHC 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 pb− 1 collected with the CMS detector. The measured cross section is σ (pp→ ZX)× 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 improves on previous measurements in the Z→ e+ e− and μ+ μ− channels. The reconstruction efficiency for hadronic τ decays is determined with a precision of 7%. |
