Book Description
The authors review the searches for supersymmetric particles achieved by the CDF and D0 collaborations at the p{bar p} Tevatron collider at FNAL, at (square root)s = 1.8 TeV and with a total integrated luminosity of 110 pb−1, per experiment. The prospects for the forthcoming run at (square root)s = 2 TeV and an integrated luminosity reaching ultimately at least 20 fb−1, are also discussed.

Book Description
We review some of the latest results on Supersymmetry searches at the Fermilab tevatron Collider. The final states for supersymmetric processes are preferably described in terms of the physical signatures produced by the particles involved. Accordingly we look at: missing transverse energy, E{sub T}, related to the presence of neutral and stable supersymmetric particles; jets, from the decay of squarks or gluinos; leptons, coming for instance from gaugino decays; photons, predicted in gauge-mediated models. We discuss here some of the most recent results on SUSY searches performed at the Fermilab Tevatron by the CDF and D0 collaborations. The CDF and D0 detectors[1, 2] collected, during the 1992-96 period (Run I), about 100 pb−1 of p{bar p} collisions. The most relevant up-grades for the current run (Run II, started in March 2001) refer mainly to the tracking and trigger system, with minor improvements to the calorimetry and muon systems.

Book Description
We review current experimental results of searches for Supersymmetry (SUSY) at the Fermilab Tevatron Collider using the Run I data collected during 1992-1996. New results from the CDF detector in the jets + missing E{sub t} and lepton-photon channels are presented. Recent results from model independent searches at D0 using the SLEUTH algorithm are reviewed. We discuss the prospects for supersymmetry searches at Run II of the Tevatron, scheduled to start in March, 2001.

Book Description
CDF and D0 detectors have already collected 1.3 fb{sup -1} of data delivered by the Tevatron collider at 1.96 TeV center-of-mass energy. We present here the various analyses that are currently testing the possibility of a supersymmetric extension of the Standard Model. No evidence for such processes have been found in luminosities that range from 300 to 800 pb{sup -1} and different limits on the different supersymmetric models are set. Constraints coming from indirect searches are also presented.

Book Description
This article presents recent results of searches for Supersymmetry using the CDF and the DO detector at the Fermilab Tevatron Collider. Described are the Tevatron searches for third generation scalar quarks and for supersymmetric signatures involving photons. All the reported results have been obtained assuming theoretical models in which R-parity is conserved.

Book Description
The results of search for Supersymmetry performed at the Tevatron Collider by the CDF and D0 collaborations are summarized in this paper. No significant deviations with respect to the Standard Model expectations were observed and constraints were set on supersymmetric parameters. Supersymmetry (SUSY), a space-time symmetry that predicts for every Standard Model (SM) particle the existence of a superpartner that differs by half a unit of spin, may provide a solution to the hierarchy problem if SUSY particles have masses lower than 1 TeV, strongly motivating the search for such particles at the Fermilab Tevatron Collider. If there is supersymmetry in nature, it must be broken and the theorized breaking mechanisms lead to many models (supergravity, gauge mediated, anomaly mediated ...) with possibly different phenomenologies. Searches performed by the CDF and D0 experiments aim at probing the extensive SUSY parameter space in terms of mass and final state.

Book Description
We discuss is the search for supersymmetry at the Fermilab Tevatron by the D0 and CDF collaborations in p{anti p} collisions at (square root)s = 1.8 TeV. The searches are performed in the jets plus E{sub T}, leptons plus E{sub T}, and photons plus E{sub T} channels. In these channels there is no excess of events over the expected backgrounds.

Book Description
The results for searches for Supersymmetry at the Tevatron Collider are summarized in this paper. They focus here on searches for chargino/neutralino and the lightest stop, as well as scenarios with R-parity violation and split supersymmetry. No significant excesses with respect to the Standard Model were observed and constraints are set on the SUSY parameter space.

Book Description
Both Tevatron experiments, D0 and CDF, have searched for signs of Supersymmetry in the present Run II data sample, using integrated luminosities of up to 260 pb{sup -1} collected in p{bar p} collisions at a center-of-mass energy of 1.96 TeV. In these proceedings, new results are presented in the search for squarks and gluinos in the jets and missing transverse energy final state, associated production of charginos and neutralinos with multilepton final states, search for the rare decay B{sub s} {yields} {mu}{mu}, searches allowing R-parity violation (muons+jets, multileptons), and searches in the gauge mediated supersymmetry breaking framework with the final state of two photons and missing transverse energy. In the absence of any significant deviation from Standard Model expectations, limits on the presence of new physics are set, which in many cases are the most stringent to date.
