We have performed a search for scalar top quark (stop) pair production in the inclusive electron-muon-missing transverse energy final state, using a sample of pp̅ events corresponding to 108.3 pb-1 of data collected with the D0 detector at Fermilab. The search is done in the framework of the minimal supersymmetric standard model assuming that the sneutrino is the lightest supersymmetric particle. For the dominant decays of the lightest stop, t̃→bχ̃1+ and t̃→bℓν̃, no evidence for signal is found. We derive cross-section limits as a function of stop ( t̃ ), chargino ( χ̃1+), and sneutrino ( ν̃) masses.
