  "abstract": "Recently, a fit to the 15 measured branching ratios of ${\\bar B} \\to D P$ decays ($B = \\{B^+, B^0, B_s^0\\}$, $D = \\{D^0, D^+, D_s^+\\}$, $P \\in \\{π, K\\}$) was performed under the assumption of flavor SU(3) symmetry [SU(3)$_F$]. A terrible fit was found: there was a $> 5σ$ disagreement with the SU(3)$_F$ limit of the Standard Model [SM$_{\\rm{SU(3)}_F}$]. It was also found that this discrepancy can be removed by adding $\\sim 20\\%$ SU(3)$_F$-breaking effects. Now, the ${\\bar B} \\to D^0 P$ amplitudes can contribute to other observables (direct and indirect CP asymmetries) if they interfere with the amplitudes for ${\\bar B} \\to {\\bar D}^0 P$ decays. This happens if the $D^0$ and ${\\bar D}^0$ decay to the same final state (e.g., $K^+ K^-$, $π^+ π^-$, $K^\\pm π^\\mp$, etc.). In this paper, we perform a combined fit of ${\\bar B} \\to D P$ and ${\\bar B} \\to {\\bar D} P$ decays, including all observables. We again find a $> 5σ$ disagreement with the SM$_{\\rm{SU(3)}_F}$, and we find that the data can be explained if $\\sim 60\\%$ SU(3)$_F$-breaking effects are included.",
