Data Analysis With the DØ Experiment Using Tau Lepton Final States

This paper gives an overview of recent results obtained by the DØ experiment at the Fermilab Tevatron pp¯ collider in analyses involving taus in the final state. The method used to identify taus decaying hadronically is described and applied to measure the Z→ττ cross-section as well as to search for new particles in the context of R-parity violated supersymmetry with λ133 coupling.
