Search for the production of scalar bottom quarks in pp̅ collisions at √s=1.96 TeV
We report on a search for direct scalar bottom quark (sbottom) pair production in pp̅ collisions at √s=1.96 TeV, in events with large missing transverse energy and two jets of hadrons in the final state, where at least one of the jets is required to be identified as originating from a b quark.
