Search for minimal supergravity in single-electron events with jets and large missing transverse energy in pp̅ collisions at √s=1.8TeV

Abstract

We describe a search for evidence of minimal supergravity (MSUGRA) in 92.7pb^-1 of data collected with the DØ detector at the Fermilab Tevatron pp̅ collider at √s=1.8TeV. Events with a single electron, four or more jets, and large missing transverse energy were used in this search. The major backgrounds are from W+jets, misidentified multijet, tt̅, and WW production. We observe no excess above the expected number of background events in our data. A new limit in terms of MSUGRA model parameters is obtained.
