Measurement of CP observables in B± → D(*)K± and B± → D(*) π ± decays using two-body D final states Alfonso Albero, Alejandro García Moreno, Paula Garrido Beltrán, Lluís Gironella Gironell, P. Gomez Fernandez, S. Graugés Pous, Eugeni Lobo Salvia, A. Mauricio, J. Vazquez Gomez, R. Marin Benito, Carla LHCb Collaboration Hadrons Gran Col·lisionador d'Hadrons Física de partícules Experiments Hadrons Large Hadron Collider (France and Switzerland) Particle physics Experiments Measurements of CP observables in B± → D(∗)K± and B± → D(∗)π ± 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 Dπ0 and Dγ final states are partially reconstructed without inclusion of the neutral pion or photon. Decays of the D meson are reconstructed in the K±π ∓, K+K−, and π +π − 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(∗)π ± with D → K∓π ± decays are the first of their kind, and a first observation of the B± → (Dπ0 )D∗ π ± 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 γ 2022-05-10T15:12:24Z 2022-05-10T15:12:24Z 2021 2022-05-10T15:12:24Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1007/JHEP04(2021)081 Journal of High Energy Physics, 2021, vol. 2021, p. 1-36 https://doi.org/10.1007/JHEP04(2021)081 cc-by (c) Alfonso Albero, Alejandro et al., 2021 https://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
