The analysis is performed in bins of phase space, which are optimised for sensitivity to local CP asymmetries. CP-violating observables that are sensitive to the angle gamma of the Unitarity Triangle are determined. The analysis requires external information on charm-decay parameters, which are currently taken from an amplitude analysis of LHCb data, but can be updated in the future when direct measurements become available. Measurements are also performed of phase-space integrated observables for B-+/- -> [K+K-pi(+)pi(-)](D)h(+/-) and B-+/- -> [pi(+)pi(-)pi(+)pi(-)](D)h(+/-) decays.", optnote="WOS:001117709800002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5945), last updated on Wed, 10 Apr 2024 12:39:59 +0000", issn="1434-6044", doi="10.1140/epjc/s10052-023-11560-5", opturl="https://arxiv.org/abs/2301.10328", opturl="https://doi.org/10.1140/epjc/s10052-023-11560-5", language="English" }
