We present the results of a search for direct pair production of scalar top (or scalar bottom) quarks followed by the decay of scalar top (or scalar bottom) quark to a charm quark (or bottom quark) and a neutralino using 88 pb–1 of data from p$$\bar{p}$$ collisions at √s = 1.8 TeV. The experimental signature is two charm (or two bottom) jets plus significant missing energy. The number of events which pass all our selection criteria is consistent with our expectations from Standard Model processes. We observe 11(5) events in the scalar top (scalar bottom) analysis and expect 14.5 ± 4.2(5.8 ± 1.8). We use a next-to-leading order scalar quark cross section calculation to excluded points, at the 95% C.L., as a function of the scalar top mass (or scalar bottom mass) and the neutralino mass
