Abstract

The CKM angle ? is determined from CP-violating observables measured in B ± ? D[K ± p ± p ± p ±]h ±, (h = K, p) 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, ? is determined to be ?=(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.
