Abstract | |||||||||
| We present a search for the pair production of scalar top quarks, t, using 995 pb−1 of data collected in pp collisions with the DÃ detector at the Fermilab Tevatron Collider at √s = 1.96 TeV. Both scalar top quarks are assumed to decay into a charm quark and a neutralino (χ01), where χ01is the lightest supersymmetric particle. This leads to a final state with two acoplanar charm jets and missing transverse energy. We find the yield of such events to be consistent with the standard model expectation, and exclude sets of t and χ01 masses at the 95% C.L. that substantially extend the domain excluded by previous searches. | |||||||||
