The abstract, sentence by sentence
Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb^-1 of pp collision data at sqrt(s) = 7 TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from >=6 to >=9 jets. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of a MSUGRA/CMSSM supersymmetric model, where, for large universal scalar mass m_0, gluino masses smaller than 840 GeV are excluded at the 95% confidence level, extending previously published limits. Within a simplified model containing only a gluino octet and a neutralino, gluino masses smaller than 870 GeV are similarly excluded for neutralino masses below 100 GeV.

In order to apply this analysis, we estimate the efficiency times acceptance in our model in the different signal regions by simulating our signal ($X̃_1^0+ X̃_1^0- j j$ production via the processes defining $σ_1$, followed by $X̃_1^0+ →Z ν̅_e$ with $BR = 1$), and then applying the cuts in [ref] .

To study constraints on such SUSY models, we reinterpret the results of the ATLAS large jet multiplicity plus missing energy search [ref] and the CMS same-sign dilepton with jets plus missing energy search [ref] .

In this case, however, the efficiency times acceptance turns out to be smaller.[From simulation via MG5 $+$ Pythia $+$ Delphes of $X̃^+-_1 X̃^-+_1 j j$ via the processes in the definition of $σ_1$ (see Subsection [ref]).] The strongest constraint arises again from signal region D (tight) in [ref] , and gives an upper bound on our model cross section of about 60 fb.
