Resumen:
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.
