Measurement of σ(pp→Z)·B(Z→ττ) in pp collisions at √(s)=1.96 TeV

We present a measurement of the inclusive production cross section for Z bosons decaying to tau leptons in pp collisions at √(s)=1.96 TeV. We use a channel with one hadronically-decaying and one electronically-decaying tau. This measurement is based on 350 pb-1 of CDF Run II data. Using a sample of 504 opposite sign eτ events with a total expected background of 190 events, we obtain σ(pp→4Z)·B(Z→ττ)=264±23(stat)±14(syst)±15(lumi) pb, in agreement with the next-to-next-to-leading order QCD prediction. This is the first CDF cross section measurement using hadronically-decaying taus in Run II
