Journal of high energy physics 04(4), 081 (2021). doi:10.1007/JHEP04(2021)081 Measurements of CP observables in B$^{��}$ ��� D$^{(*)}$K$^{��}$ and B$^{��}$ ��� D$^{(*)}$��$^{��}$ decays are presented, where D$^{(���)}$ indicates a neutral D or D$^{���}$ meson that is an admixture of meson and anti-meson states. Decays of the D$^{(���)}$ meson to the D��$^{0}$ and D�� final states are partially reconstructed without inclusion of the neutral pion or photon. Decays of the D meson are reconstructed in the K$^{��}$��$^{���}$, K$^{+}$K$^{���}$, and ��$^{+}$��$^{���}$ final states. The analysis uses a sample of charged B mesons produced in proton-proton collisions and collected with the LHCb experiment, corresponding to integrated luminosities of 2.0, 1.0, and 5.7 fb$^{���1}$ taken at centre-of-mass energies of 7, 8, and 13 TeV, respectively. The measurements of partially reconstructed B$^{��}$ ��� D$^{(*)}$K$^{��}$ and B$^{��}$ ��� D$^{(���)}$��$^{��}$ with D ��� K$^{���}$��$^{��}$ decays are the first of their kind, and a first observation of the B$^{��}$ ��� $ {\left(D{\pi}^0\right)}_{D^{\ast }}{\pi}^{\pm } $ decay is made with a significance of 6.1 standard deviations. All CP observables are measured with world-best precision, and in combination with other LHCb results will provide strong constraints on the CKM angle ��.[graphic not available: see fulltext] Published by SISSA, [Trieste]
