Abstract

A search for squarks and gluinos performed by the CDF and D0 collaborations is presented. The sample taken during the RunII of the Fermilab TeVatron collider at {radical}s = 1.96 TeV is used. Supersymmetry (SUSY) is one of the most promising ways to solve crucial problems of the Standard Model (SM). This spacetime symmetry links bosons to fermions by introducing supersymmetric partners (sparticles) to all SM particles: squarks and gluinos are SUSY partners of quarks and gluons. The mass difference between the squark mass eigenstates depend on the mass of the corresponding quark. Hence squarks are (to a good approximation) mass degenerate for the two first generations whereas a (potentially) large mixing may appear for the third family, leading to a light stop. The former case corresponds to squarks and gluinos searches whereas dedicated searches for stop are performed for the latter.

Search for the Production of Gluinos and Squarks with the CDF II Experiment at the Tevatron Collider

Thesis/Dissertation De Lorenzo, Gianluca

This thesis reports on two searches for the production of squarks and gluinos, supersymmetric partners of the Standard Model (SM) quarks and gluons, using the CDF detector at the Tevatron √s = 1.96 TeV p$$\bar{p}$$ collider. An inclusive search for squarks and gluinos pair production is performed in events with large E_T and multiple jets in the final state, based on 2 fb^-1 of CDF Run II data. The analysis is performed within the framework of minimal supergravity (mSUGRA) and assumes R-parity conservation where sparticles are produced in pairs. The expected signal is characterized by the production of multiple jetsmore »« less

Search for Third Generation Squarks in the Missing Transverse Energy plus Jet Sample at CDF Run II

Thesis/Dissertation Marono, Miguel

The twentieth century leaves behind one of the most impressive legacies, in terms of human knowledge, ever achieved. In particular the StandardModel (SM) of particle physics has proven to be one of the most accurate descriptions of Nature. The level of accuracy of some theoretical predictions has never been attained before. It includes the electromagnetic interaction, and the weak and strong force, developing the Lagrangian from symmetry principles. There are two different types of fundamental constituents of Nature, in the framework of the Standard Model: bosons and fermions. Bosons are those particles responsible for carrying the interactions among the fermions,more »« less

Search for gluino and squark production in multi-jets plus missing transverse energy final states at the Tevatron using the CDF detector

Thesis/Dissertation Portell i Bueso, Xavier

In this thesis, the results of the search for squarks and gluinos in multiple jets plus missing transverse energy final states have been presented. No evidence of these new particles have been found in 371 pb^-1 of CDF Run II data. New limits have been set which exclude gluino masses below 220 GeV and, in the region where M_{$$\tilde{g}$$} ~ M_{$$\tilde{q}$$}, masses below 380 GeV/c² are excluded. These limits are valid in a mSUGRA scenario with tan β = 5, A = 0 and μ < 0 assuming the lightest four squark flavours degenerate in mass. To obtain these resultsmore »« less

SUSY searches at the Tevatron

Conference Jaffre, Michel

The Tevatron collider has provided the CDF and D0 collaborations with large datasets as input to a rich program of physics beyond the standard model. The results presented here are from recent searches for SUSY particles using up to 6 fb{sup -1} of data. Supersymmetry (SUSY) [1] is one of the most favored theories beyond the standard model (SM). Each SM particle is associated to a sparticle whose spin differs by one half unit. This boson-fermion symmetry is obviously broken by some unknown mechanism. Even in the minimal supersymmetric extension of the SM (MSSM [2]) there are a large numbermore »« less

Non-inclusive searches for squarks and gluinos at the Tevatron

Conference Biscarat, Catherine

Recent results from the CDF and D0 Collaborations on searches for squarks and gluinos at the Run II of the Fermilab Tevatron collider are presented. This review covers searches for final states involving specific mass hierarchies. The analyzed datasets correspond to an integrated luminosity of 300-1000 pb{sup -1} collected from proton anti-proton collisions at a center-of-mass energy of 1.96 TeV. No significant deviations from the Standard Model expectations are observed and limits on parameters of supersymmetry are set in generic MSSM and in specific mSUGRA scenarios.
