Abstract

This contribution reports on preliminary measurements on searches for squarks and gluinos at CDF and D0 detectors in p{bar p} collisions at {radical}s = 1.96 TeV. The analyses are performed using event topologies with multiple jets and large missing energy in the final state. The mSUGRA scenario and R-parity conservation is assumed. No excess with respect to the Standard Model predictions is observed and new limits on the gluino and squark masses are extracted.

Searches for squarks and gluinos at CDF and D0 detectors

Portell, Xavier ; /Barcelona, IFAE

This contribution reports on preliminary measurements of searches for squarks and gluinos at CDF and D0 detectors in p{bar p} collisions at {radical}s = 1.96 TeV using 1 fb{sup -1} of data. The analyses are optimized for event topologies with multiple jets and large missing transverse energy in the final state. No excess with respect to the Standard Model predictions is observed and new limits on the gluino and squark masses are extracted in a mSUGRA scenario with R-parity conservation.

Searches for Squarks and Gluinos at CDF and DO Detectors

Portell, Xavier - AIP Conference Proceedings

This contribution reports on preliminary measurements on searches for squarks and gluinos at CDF and DO detectors in pp-bar collisions at {radical}(S) = 1.96 TeV. The analyses are performed using event topologies with multiple jets and large missing energy in the final state. The mSUGRA scenario and R-parity conservation is assumed. No excess with respect to the Standard Model predictions is observed and new limits on the gluino and squark masses are extracted.

Search for squarks and gluinos in p{bar p} collisions at the D0 detector with the jets and missing energy signature

The D0 Collaboration

A search for squarks and gluinos has been performed using the D{null} detector at {radical}s = 1.8 TeV Tevatron {ital p{anti p}} collider. Data from the 1992-1993 collider run corresponding to an integrated luminosity of 13.5 pb{sup -1} were examined via the missing {ital E{sub T}} plus jets signature with two separate analyses. No events above the Standard Model backgrounds were observed.

Search for Squarks and Gluinos with the D0 detector

Uzunyan, Sergey A. ; /Northern Illinois U.

We report on D0 searches for scalar quarks ({tilde q}) and gluinos ({tilde g}), the superpartners of quark and gluons, in topologies involving jets and missing transverse energies. Data samples obtained with D0 detector from p{bar p} collisions at a center-of-mass energy of 1.96 TeV corresponding to an integrated luminosities of 1-4 fb{sup -1} were analyzed. No evidence for the production of such particles were observed and lower limits on squarks and gluino masses were set.

Search for squarks and gluinos using data from the D0 detector at the Tevatron

Biscarat, Catherine ; /Lyon, IPN

A search for squarks and gluinos is performed in the topology of multijet events accompanied by large missing transverse energy in 2.1fb{sup -1} of p{bar p} collision data collected using the D0 detector at the Fermilab Tevatron Collider at a center of mass energy of 1.96 TeV. About half of this dataset is specifically analyzed for events involving at least one tau lepton decaying hadronically in addition. No deviation from the Standard Model expectation is observed and the analyses are combined to set limits on the squark and gluino masses and on parameters of minimal supergravity.
