Search for top squark pair production in the dielectron channel

This report describes the first search for top squark pair production in the channel $t_{1}t{\overline{̃}}_1\to b\overline{b}{\tilde{\chi }}_1^{+}{\tilde{\chi }}_1^{-}\to \mathrm{ee}$+jets+$E_T$ using $74.9\pm 8.9$ pb${}^{-1}$ of data collected using the DØ detector. A 95% confidence level upper limit on $\sigma \cdot B$ is presented. The limit is above the theoretical expectation for $\sigma \cdot B$ for this process, but does show the sensitivity of the current DØ data set to a particular topology for new physics.
