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{−5.8}{+6.0}{−0.6}{+0.6}{−4.3}{+6.7})°, 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.
