Abstract
We present a search for pair produced top squarks, the supersymmetric partners of the top quark, using the DO detector at the Fermilab Tevat ron p (p) over bar collider. We consider a scenario in which the light er of the two top squarks (t) over tilde(1) decays with 100% branching fraction to a charm quark and the lightest neutralino <(chi)over tild e>(0)(1) yielding a signal of two acollinear jets with missing transve rse energy. 3 events while we expect 3.5 +/- 1.2 events from the known standard model processes. the 95% confidence level a significant regi on of the m((t) over tilde 1)-m(<(chi)over tilde>1)(0) parameter space . The highest m((t) over tilde 1) value we exclude is 93 GeV/c(2) with a corresponding m(<(chi)over tilde>1)(0) value of 8 GeV/c(2).
