Hunt for New Physics at D0: from Run I to Run II ================================================ Greg Landsberg Brown University Abstract: --------- In this talk I will cover a large number of recent searches for physics beyond the Standard Model carried out by the D0 experiment at the Fermilab Tevatron. Topics that I'll cover include searches for the R-parity conserving and violating SUSY, leptoquarks of all three generations, quark-lepton compositeness, Higgs boson with non-standard coupling to fermions, technicolor, etc. While the last Tevatron run has not shown any statistically significant deviations from the Standard Model, the new run with the upgraded accelerator and detectors, scheduled to start in early 2001, will offer an excellent opportunity to find new physics beyond the Standard Model. I'll cover some of the most exciting possibilities that D0 is going to explore, including searches for supersymmetry in the gauge- and anomaly-mediated SUSY breaking cases, search for large spatial extra dimensions, and search for massive quasi-stable particles.
