We present a measurement of the inclusive production cross-section for Z bosons decaying to tau leptons in p{bar p} collisions at {radical}s = 1.96 TeV. We use a channel with one hadronically-decaying and one electronically-decaying tau. This measurement is based on 350 pb{sup -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{bar p} {yields} Z) {center_dot} {Beta}(Z {yields} {tau}{tau}) = 263 {+-} 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.
