 (Click each plot for EPS) Distribution of missing transverse energy in observed same-sign dilepton events with at least two jets and expected backgrounds. (Click each plot for EPS) Distribution of $H_T$ in observed same-sign dilepton events with at least two jets and expected backgrounds. (Click each plot for PDF) Feynman diagrams of gluino production with subsequent decays leading to same-sign dileptons. (Click each plot for PDF) Feynman diagrams of squark pair production with subsequent decays leading to same-sign dilepton (left), trilepton (center), and four-lepton (right) final states. Diagrams are similar for gluino pair production (not shown).
