A Multilepton signal for supersymmetric particles in Tevatron data?

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: $\tilde{q}\to q\tilde{\chi }$, $\tilde{\chi }\to \nu \tilde{\ell }$, $\tilde{\ell }\to \ell {\tilde{\chi }}_1^0$. Such a supersymmetric origin also leads to events with large transverse missing energy and either 0, 1, 2 same-sign, or 3 isolated leptons.
