First observation of the B+D+sDsK+ decay / LHCb Collaboration
The B+D+sDsK+ decay is observed for the first time using proton-proton collision data collected by the LHCb detector at centre-of-mass energies of 7, 8 and 13TeV, corresponding to an integrated luminosity of 9fb1. Its branching fraction relative to that of the B+D+DK+ decay is measured to be B(B+D+sDsK+)B(B+D+DK+)=0.525±0.033±0.027±0.034, where the first uncertainty is statistical, the second systematic, and the third is due to the uncertainties on the branching fractions of the D±sKK±π± and D±Kπ±π± decays.

The decay BΛ+cˉΛcK is studied in proton-proton collisions at a center-of-mass energy of s=13 TeV using data corresponding to an integrated luminosity of 5 fb1 collected by the LHCb experiment. In the Λ+cK system, the Ξc(2930)0 state observed at the BaBar and Belle experiments is resolved into two narrower states, Ξc(2923)0 and Ξc(2939)0, whose masses and widths are measured to be m(Ξc(2923)0)=2924.5±0.4±1.1MeV,m(Ξc(2939)0)=2938.5±0.9±2.3MeV,Γ(Ξc(2923)0)=0004.8±0.9±1.5MeV,Γ(Ξc(2939)0)=0011.0±1.9±7.5MeV, where the first uncertainties are statistical and the second systematic.

Observation of a resonant structure near the D+sDs threshold in the B+D+sDsK+ decay / LHCb Collaboration
An amplitude analysis of the B+D+sDsK+ decay is carried out to study for the first time its intermediate resonant contributions, using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV. A near-threshold peaking structure, referred to as X(3960), is observed in the D+sDs invariant-mass spectrum with significance greater than 12 standard deviations. [...]

Measurement of the CKM angle γ with B±D[Kπ±π±π]h± decays using a binned phase-space approach / LHCb Collaboration
The CKM angle γ is determined from CP-violating observables measured in B±D[Kπ±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 13TeV, corresponding to a total integrated luminosity of 9fb1, γ is determined to be γ=(54.8+6.05.8+0.60.6+6.74.3), 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..

Multidifferential study of identified charged hadron distributions in Z-tagged jets in proton-proton collisions at s=13 TeV / LHCb Collaboration
Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a Z boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 <pT<100 GeV and in the pseudorapidity range 2.5<η<4. [...]
