The analysis shows no excess of events over the Standard Model expectations. As a result, exclusion limits were placed on searches for squarks and gluinos in the Constrained Minimal Supersymmetric extension of the Standard Model (CMSSM).
The Standard Model is thought to be superseded at higher energies by a more complete theory, such as CMSSM. If supersymmetric (SUSY) particles such as squarks or gluinos are produced in collisions at the LHC, we expect them to decay rapidly into stable particles known as lightest supersymmetric particles (LSP). The LSP, which is predicted to be neutral and weakly interacting, will leave no signature in the detector, and its presence has to be inferred from missing transverse energy (MET).
In this paper, CMS searched for signatures of supersymmetry (SUSY) in events with two or more energetic particle jets and missing transverse energy.
Group: Supersymmetric Physics (SUS)
Collisions: pp
Centre-of-mass energy: 7 TeV
Data sample: 1.14 ± 0.05 fb–1
Measurement/Limit:
CMSSM squark masses are excluded below 1.1 TeV at 95% confidence level (CL).
CMSSM gluino masses are excluded below 1.1 TeV at 95% CL, when the universal scalar mass parameter, m0, has a value of less than 500 GeV.
