Search for squarks and gluinos using data from the DO/ detector at the Tevatron

A search for squarks and gluinos is performed in the topology of multijet events accompanied by large missing transverse energy in 2.1 fb−1 of pp collision data collected using the DO/ detector at the Fermilab Tevatron Collider at a center of mass energy of 1.96 TeV. About half of this dataset is specifically analysed for events involving at least one tau lepton decaying hadronically in addition. No deviation from the Standard Model expectation is observed and the analyses are combined to set limits on the squark and gluino masses and on parameters of minimal supergravity.
