Invariant-mass distributions for the (left) $\Bpm\to\D\Kpm$ and (right) $\Bpm\to\D\pipm$ selections, for the $\D\to\Kp\Km\pip\pim$ decay. The data are shown as black points and the blue curve is the fit result. The square brackets in the legend denote particles that are not reconstructed.

Graphical representation of the \CP-violating observables for the (left) $\Bpm\to\D\Kpm$ and (right) $\Bpm\to\D\pipm$ decay modes, assuming amplitude-model predictions of $c_i$ and $s_i$. The 1$\sigma$ and 2$\sigma$ contours shown represent the statistical uncertainties and correspond to $68.3\%$ ($\Delta\chi^2 = 2.30$) and $95.5\%$ ($\Delta\chi^2 = 6.18$) confidence intervals.

Fractional bin asymmetries for the (left) $\Bpm\to\D\Kpm$ and (right) $\Bpm\to\D\pipm$ decays. The data are overlaid with the fit result and the prediction without \CP violation.

Interpretation of the binned and phase-space (`PS') integrated measurements in terms to the underlying physics parameters. The 1$\sigma$ and 2$\sigma$ contours are shown, which correspond to $68.3\%$ ($\Delta\chi^2 = 2.30$) and $95.5\%$ ($\Delta\chi^2 = 6.18$) confidence intervals, respectively. Also shown is the result from the analysis of other decay modes at LHCb (`LHCb 2021')~\cite{LHCb-PAPER-2021-033}.
