  A search for the pair production of scalar top quarks, or stops, has been
performed in 360 pb-1 of data from p pbar collisions at a center-of-mass energy
of 1.96 TeV, collected by the D0 detector at the Fermilab Tevatron collider.
The stop decay mode considered is stop into c chi, where chi is the lightest
supersymmetric particle. The topology analyzed therefore consists of a pair of
acoplanar heavy-flavor jets with missing transverse energy. The data and
standard model expectation are in agreement, and a 95% C.L. exclusion domain in
the stop and chi mass plane has been determined, extending the domain excluded
by previous experiments.
