Recent results on searches for new phenomena from D0

Do is taking data since April 2001 and has recorded, for Physics analysis, an integrated luminosity of around 83 pb(-1) in Run II of the Fermilab Tevatron, at a center-of-mass energy of 1.96 TeV. Searches for phenomena beyond the Standard Model are presented in a variety of channels and models. Lepton identification is a key element in Searches. Evidence is shown, through a search for Z in tautau decays, that DO is able to identify it.
