Measurement of σ(pp̄→Z)·Br(Z→ττ) at √s=1.96 TeV
We present a measurement of the cross section for Z production times the branching fraction to τ leptons, σ·Br(Z → τ+τ-), in pp̄ collisions at √s = 1.96 TeV in the channel in which one τ decays into μνμν τ, and the other into hadrons + ντ or eνeντ. The data sample corresponds to an integrated lumino...
