“…The analysis is insensitive to light gluinos, mg ≤ O(40 GeV). However, various other experiments, in particular those at the CERN SPS [2,3] exclude most of the region below 40 GeV, except for a narrow range around 3-5 GeV/c 2 [4].…”

We discuss the pair production of gluinos in electron-positron annihilation at LEP, in a model with soft supersymmetry breaking, allowing for mixing between the squarks. In much of the parameter space of the Minimal Supersymmetric Model (MSSM) the cross section corresponds to a Z branching ratio above 10 −5 , even up to 10 −4 . A non-observation of gluinos at this level restricts the allowed MSSM parameter space. In particular, it leads to lower bounds on the soft mass parameters in the squark sector.

“…For gluinos that decay directly or through a one step cascade into the LSP and two jets, the mass range mg ≤ 205 GeV is disfavored by the ATLAS searches, regardless of the mass of the LSP. In some cases the coverage extends up to mg 295 GeV, already surpassing the Tevatron's reach for compressed supersymmetry spectra.1 UA2 provides some of the most extensive discussion on gluino limits away from gaugino mass unification [5].…”

Itʼs on: Early interpretations of ATLAS results in jets and missing energy searches

The first search for supersymmetry from ATLAS with 70 nb −1 of integrated luminosity extends the Tevatron' s reach for colored particles that decay into jets plus missing transverse energy. For gluinos that decay directly or through a one step cascade into the LSP and two jets, the mass range mg ≤ 205 GeV is disfavored by the ATLAS searches, regardless of the mass of the LSP. In some cases the coverage extends up to mg 295 GeV, already surpassing the Tevatron's reach for compressed supersymmetry spectra.1 UA2 provides some of the most extensive discussion on gluino limits away from gaugino mass unification [5].

“…This occurs, for example, in supersymmetry [1] and Universal Extra Dimensions [2], as well as Randall-Sundrum [3] and Little Higgs models [4]. As a result, jets plus missing transverse energy (E T ) is a promising experimental signature for new phenomena [5,6,7,8,9].…”

Searching for directly decaying gluinos at the Tevatron

et al. 2008

This letter describes how to perform searches over the complete kinematically-allowed parameter space for new pair-produced color octet particles that each subsequently decay into two jets plus missing energy at the Tevatron. This letter shows that current searches can miss otherwise discoverable spectra of particles due to CMSSM-motivated cuts. Optimizing the HT and ET cuts expands the sensitivity of these searches.
