Recent results on searches for new physics at Run II of the Tevatron are reported. The searches cover many different final states and previous hints of signals, but all analyses have at this point led to negative results.

This paper reports on recent searches for exotic particles by the CDF and D.

The Fermilab Tevatron collider experiments CDF and D0 collected more than 100 pb−1 of data at (square root)(s) = 1.8 TeV during Run I (1992-1995). Results of searches for new phenomena (exotics) are presented, covering supersymmetry, leptoquarks, technicolor, and quark compositeness. In each case, no discrepancy with the Standard Model is observed, and stringent limits on new physics predicted by these models are extracted. Parameters for Run II of the Tevatron are given along with projections of search reaches for this upcoming run.

The authors present results of searches for signs of physics beyond the Standard Model. The focus of this paper is on analyses not driven by SUSY models. Most of the presented results are based on (almost equal to) 2 fb−1 of data and obtained since summer of 2007. No significant excess of data over predicted background is observed. They report kinematic distributions, data and background counts, as well as limits on some parameters of selected models of new physics.

Searches for new particles have been conducted at the Tevatron using data from the 1992{ 1996 data sets. Brief descriptions of searches for vector leptoquarks, Dirac monopoles and technicolor particles are presented here.
