  • Beschreibung: <jats:title>A<jats:sc>bstract</jats:sc> </jats:title> <jats:p>A search is presented for new particles decaying to large numbers (7 or more) of jets, with missing transverse momentum and no isolated electrons or muons. This analysis uses 20.3 fb<jats:sup>−1</jats:sup> of <jats:italic>pp</jats:italic> collision data at <jats:inline-formula> <jats:tex-math>$ \sqrt{s}=8 $</jats:tex-math> </jats:inline-formula> TeV collected by the ATLAS experiment at the Large Hadron Collider. The sensitivity of the search is enhanced by considering the number of <jats:italic>b</jats:italic>-tagged jets and the scalar sum of masses of large-radius jets in an event. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of various simplified supersymmetry-inspired models where gluinos are pair produced, as well as an mSUGRA/CMSSM model. </jats:p>
