Search for squarks and gluinos in events with jets and missing transverse energy in pp¯ collisions at √s=1.96TeV

Abstract

The results of a search for squarks and gluinos using data from collisions recorded at a center-of-mass energy of 1.96 TeV by the D∅ detector at the Fermilab Tevatron Collider are reported. The topologies analyzed consist of acoplanar-jet and multijet events with large missing transverse energy. No evidence for the production of squarks or gluinos was found in a data sample of 310 pb^-1. Lower limits of 325 and 241 GeV were derived at the 95% C.L. on the squark and gluino masses, respectively, within the framework of minimal supergravity with tanβ=3, A₀=0, and μ<0.
