Measurement of the CKM angle γ with B ± → D[K ∓ π ± π ± π ∓]h ± decays using a binned phase-space approach

Abstract The CKM angle γ is determined from CP-violating observables measured in B ± → D[K ∓ π ± π ± π ∓]h ± , (h = K, π) decays, where the measurements are performed in bins of the decay phase-space of the D meson. Using proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to a total integrated luminosity of 9 fb −1, γ is determined to be γ = 54.8 + 6.0 − 5.8 + 0.6 − 0.6 + 6.7 − 4.3 ∘ , $$ \gamma ={\left(54.8\begin{array}{c}+6.0\\ {}-5.8\end{array}\begin{array}{c}+0.6\\ {}-0.6\end{array}\begin{array}{c}+6.7\\ {}-4.3\end{array}\right)}^{\circ }, $$ where the first uncertainty is statistical, the second systematic and the third from the external inputs on the coherence factors and strong phases of the D-meson decays
