Search for top squark pair production in the dielectron channel

Abstract

This report describes the first search for top squark pair production in the channel t₁t̅^~ ₁→bb̅→χ₁⁺χ₁^-→ee+jets+E_T using 74.9±8.9 pb^-1 of data collected using the DØ detector. A 95% confidence level upper limit on σ·B is presented. The limit is above the theoretical expectation for σ·B for this process, but does show the sensitivity of the current DØ data set to a particular topology for new physics.
