This thesis reports on a search for evidence of production and decay of squarks (q) and gluinos (g) of Minimal Supergravity (mSUGRA) in p{bar p} collisions at a center of mass energy of 1.8 TeV using the D0 detector at the Fermi National Accelerator Laboratory. Data corresponding to 79.2 ± 4.2 pb−1 were examined for events with large missing transverse energy (E{sub T}), three or more jets, high energy leading jet, and the absence of isolated leptons. Since no events were observed in excess of Standard Model background predictions, limits are placed in the mSUGRA M0 - M{sub {1/2}} plane for fixed parameters tan? = 2, A{sub o} = 0, and?

The results of a search for squarks and gluinos using data from ppbar collisions recorded at a center-of-mass energy of 1.96 TeV by the D0 detector at the Fermilab Tevatron Collider are reported. The topologies analyzed consist of acoplanar-jet and multijet events with large missing transverse energy. No evidence for the production of squarks or gluinos was found in a data sample of 310 pb-1. Lower limits of 325 and 241 GeV were derived at the 95% C.L. on the squark and gluino masses, respectively, within the framework of minimal supergravity with tan[beta]=3, A0=0, and mu

In this paper, a search for squarks and gluinos in final states containing hadronic jets, missing transverse momentum but no electrons or muons is presented. The data were recorded in 2015 by the ATLAS experiment in √s=13 TeV proton–proton collisions at the Large Hadron Collider. No excess above the Standard Model background expectation was observed in 3.2 fb-1 of analyzed data. Results are interpreted within simplified models that assume R-parity is conserved and the neutralino is the lightest supersymmetric particle. An exclusion limit at the 95 % confidence level on the mass of the gluino is set at 1.51 TeV for a simplified model incorporating only a gluino octet and the lightest neutralino, assuming the lightest neutralino is massless. For a simplified model involving the strong production of mass-degenerate first- and second-generation squarks, squark masses below 1.03 TeV are excluded for a massless lightest neutralino. Finally, these limits substantially extend the region of supersymmetric parameter space excluded by previous measurements with the ATLAS detector.

Based on 7.1 pb−1 of single interaction event data collected by the DO Detector at Fermilab during the 1992--1993 p{bar p} collider run at (square root)s = 1.8 TeV, results are presented of a search for supersymmetric partners of the quark and gluon, the squark and gluino, using missing E{sub T} and jets as the signature. Limits are set on the squark and gluino masses in the context of the Minimal Supersymmetric Standard Model including the effect of cascade decays of the squark and gluino.

Using data corresponding to an integrated luminosity of 79 pb−1, D0 has searched for events containing multiple jets and large missing transverse energy in p{bar p} collisions at √s = 1.8 TeV at the Fermilab Tevatron collider. Observing no significant excess beyond what is expected from the standard model, they set limits on the masses of squarks and gluinos and on the model parameters m0 and m12, in the framework of the minimal low-energy supergravity models of supersymmetry. For tan [beta] = 2 and A0 = 0, with [mu]
