Supersymmetry at Dø and other new phenomena searches in Run II

The RunII of the Do experiment was started in March 2001. The first preliminary results on searches for new physics are presented, with a luminosity of ∼ 10 pb−1 from the data collected in 2001-2002. We report results in mSUGRA (jets + missingEt channel), GMSB (diphotons), RPV (trileptons and like sign dileptons) and large extra dimensions (dielectrons and diphotons).
