Abstract
We report on a search for direct scalar bottom quark (sbottom) pair production in collisions at , 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 quark. The study uses a collider detector at Fermilab Run II data sample corresponding to of integrated luminosity. The data are in agreement with the standard model. In an -parity conserving minimal supersymmetric scenario, and assuming that the sbottom decays exclusively into a bottom quark and a neutralino, 95% confidence-level upper limits on the sbottom pair production cross section of 0.1 pb are obtained. For neutralino masses below , sbottom masses up to are excluded at 95% confidence level.
