Book excerpt: Recent results of searches for new physics in top events at the Tevatron are presented. In case of CDF three searches are discussed using 6 to 8.7 fb−1 of data, with the latter being the final CDF data sample available for this kind of analysis. CDF carried out a search for Top + jet resonance production, dark matter production in association with single top and boosted tops. No signs of new physics are observed and instead upper limits are derived. D0 used 5.3 fb−1 of data and searched for a narrow resonance in t{bar t} production and a time dependent t{bar t} cross section, which would reveal a violation of Lorentz invariance. However, no signs for deviations from standard model are seen and instead upper limits for non-standard model contributions are calculated.
