Searches for new physics at the Tevatron
V. Buescher
Abstract
Recent results of searches for new phenomena using data collected in Run I by the CDF and D0 experiments are presented. D0 set limits for top squarks decaying into b+l+sneutrino significantly beyond the reach of previous analyses in this channel (mstop>140GeV at 95% C.L. for msnu=45GeV). CDF exclude top squarks decaying into b+tau for masses below 111GeV. In addition, D0 have analyzed photon and electron pair production to search for effects of large extra dimensions. No evidence is found, resulting in limits on the effective Planck scale of 1.1 TeV. Finally, D0 have used a model-independent search strategy for new physics at high pt to test more than 32 different final states for evidence of a signal. Observations in all samples are found to be consistent with expectations from the Standard Model.
