The Run II physics programme of the Tevatron is proceeding with more than 300 pb{sup -1} of analysis quality data, collected at a center-of-mass energy of 1.96 TeV. Searches for supersymmetric particles are starting to set new limits, improving over the LEP and Run I results and exploring new regions of parameter space. They present recent results in Supersymmetry with the upgraded CDF and D0 detectors and give some prospects for the future of these searches.

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.

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.

Download Supersymmetry at the Tevatron?. Book in PDF, ePub and Kindle
These lectures contain an introduction to the search for supersymmetry at hadron colliders. The Tevatron is one of high-energy physics most sophisticated tools. The high center-of-mass energy of its proton-antiproton collisions makes it an ideal place to search for physics beyond the Standard Model, such as supersymmetry. Two experiments, CDF and D0, completed a long data taking period in summer of 1995, yielding over 100 pb−1 of proton-antiproton interactions. The data recorded by the experiments are still being analyzed. The lectures outline the strategies in the search for supersymmetry at the Tevatron and examine the major analyses in detail. Results obtained by the two experiments are included where available.

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.

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.

Download Search for Supersymmetry at the Tevatron Using the Trilepton Signature Book in PDF, ePub and Kindle
This dissertation describes a search for the associated production of the supersymmetric particles, the chargino and the neutralino, through their R-parity conserving decays to three leptons and missing energy. This search is carried out using the data collected at the CDF experiment at the Tevatron's = 1.96 TeV p-anti-p collider at Fermilab. The results are obtained by combining five independent channels with varying signal to background ratio. Overall, a total of 6.4 [plus minus] 1.1 background events from standard model processes and 11.4 [plus minus] 1.1 signal events for a particular choice of mSUGRA model parameters are expected. The observation of 7 events in data is consistent with the standard model background expectation, and the mSUGRA model is constrained. Limits are set on the cross section of Chargino-Neutralino pair production, and a limit on the mass of the chargino is extracted. A method of obtaining model-independent results is also discussed.

We report the results of searches for new physics in events with two photons and large missing transverse energy collected with both detectors at the Fermilab Tevatron collider. Several models of physics beyond the Standard Model motivate searches in this final state, in particular supersymmetry (SUSY) with gauge-mediated supersymmetry breaking. The D0 collaboration interprets also its search in the framework of universal extra dimensions (UED) with gravity-mediated Kaluza-Klein excitation decays. The results presented use 2.6 fb−1 (CDF) and 6.3 fb−1 (D0) of data collected at the Fermilab Tevatron collider.
