Abstract

The CDF and D0 Collaborations have both reported unusual events in the dilepton $+$ jets sample with very high lepton and missing transverse energies. It is possible, but very unlikely, that these events originate from top quark pair production; however, they have characteristics that are better accounted for by decays of supersymmetric quarks with mass in the region of 300 GeV: $\tilde{q} \to q \tilde{χ}$ , $\tilde{χ} \to ν \tilde{ℓ}$ , $\tilde{ℓ} \to ℓ {\tilde{χ}}_{1}^{0}$ . Such a supersymmetric origin also leads to events with large missing transverse energy and either 0, 1, 2 same-sign, or 3 isolated charged leptons.
