 | The distribution of \HT for all channels combined after the full selection except for the \HT requirement itself. The shaded band represents the total uncertainty in the predicted backgrounds. The final bin includes all overflow events. The pull is defined as the difference between the observed and expected values divided by the total uncertainty. |
 | Expected and observed 95\% CL limits on the $\Tft$ production cross section times the branching fraction for decay to same-sign dileptons. The $1\sigma$ and $2\sigma$ combined statistical and systematic expected variations are shown as yellow (light) and green (dark) bands, respectively. |
 | The distribution of \HT for all channels combined, after after the requirement of same-sign dileptons, the \cPZ-boson veto, and a requirement of at least two jets. The shaded band represents the total uncertainty in the predicted backgrounds. The final bin includes all overflow events. The pull is defined as the difference between the observed and expected values divided by the total uncertainty. |
 | Expected and observed 95\% CL limits on the $\Tft$ production cross section times the branching fraction for decay to same-sign dileptons. The $1\sigma$ and $2\sigma$ combined statistical and systematic expected variations are shown as yellow (light) and green (dark) bands, respectively. |
 | The distribution of the reconstructed $\Tft$ mass for the data, the background, and three signal mass points. The background is dominated by the contribution due to non-prompt leptons and also contains much smaller contributions due to $\ttbar \PW$, $\ttbar\PW\PW$, $\ttbar\cPZ$, $\PW\PW\PW$, same-sign $\PW\PW$, and charge misidentification. The shaded band represents the total uncertainty in the predicted background. |
