Representative Feynman diagrams for the $\cPqt\PW$ (left panel) and \ttbar (right panel) production at leading order. The upper row presents the SM diagrams, the middle and lower rows present diagrams corresponding to the $O_{\phi \cPq}^{(3)}$, $O_{\cPqt\PW}$,$O_{\cPqt\cPG}$, $O_{\cPG}$ and $O_{\mathrm {u/cG}}$ contributions.

The observed number of events and SM background predictions in the search regions of the analysis for the $\Pe\Pe$ (upper left), $\Pgm\Pgm$ (upper right), and $\Pe\Pgm$ (lower) channels. The hatched bands correspond to the quadratic sum of statistical and systematic uncertainties in the event yield for the SM background predictions. The ratios of data to the sum of the predicted yields are shown at the bottom of each plot. The narrow hatched bands represent the contribution from the statistical uncertainty in the MC simulation.

Observed (solid) and expected (dotted) log likelihoods for the effective couplings: C$_{\cPG}$ (upper left), C$_{\cPqt\cPG}$ (upper right), C$_{\cPqt\PW}$ (middle left), C$_{\phi \cPq}$ (middle right), C$_{\cPqu\cPG}$ (lower left), and C$_{\cPqc\cPG}$ (lower right). The dashed curves represent fits to the observed data with the variations of normalization due to the theoretical uncertainties.
