Resumen

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)∘, 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.
