Searches for new physics at DO

We present results on four searches for new physics at Dempty set. We look for Supersymmetry in events with two photons and is not an element of(T), excited quarks or heavy gauge bosons decaying to di-jets, first generation leptoquarks in which a produced pair decay to two electrons and two jets, and a heavy neutral scalar particle produced in association with a W boson and decaying to b (b) over bar. All of our data are consistent with background predictions and 95% confidence limits are shown.
