Abstract
We present a measurement of the inclusive production cross section for Z bosons decaying to tau leptons in p (p) over bar collisions at root 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 e tau events with a total expected background of 190 events, we obtain sigma(p (p) over bar -> 4Z)center dot B(Z ->tau tau)=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.
