Search for prompt production of pentaquarks in charm hadron final states / LHCb Collaboration
A search for hidden-charm pentaquark states decaying to a range of ΣcˉDΣc¯D and Λ+cˉDΛ+c¯D final states, as well as doubly-charmed pentaquark states to ΣcDΣcD and Λ+cDΛ+cD, is made using samples of proton-proton collision data corresponding to an integrated luminosity of 5.7fb15.7fb1 recorded by the LHCb detector at s=13TeVs=13TeV. Since no significant signals are found, upper limits are set on the pentaquark yields relative to that of the Λ+cΛ+c baryon in the Λ+cpKπ+Λ+cpKπ+ decay mode. [...]

Observation and branching fraction measurement of the decay ΞbΛ0bπΞbΛ0bπ / LHCb Collaboration
The decay ΞbΛ0bπΞbΛ0bπ is observed using a proton-proton collision data sample collected at center-of-mass energy s=13s=13 TeV with the LHCb detector, corresponding to an integrated luminosity of 5.5 fb11. This process is mediated by the suˉudsu¯ud quark-level transition, where the bb quark in the ΞbΞb baryon is a spectator in the decay. [...]

Measurement of the CKM angle γγ using the B±Dh±B±Dh± channels / LHCb Collaboration
A measurement of the CPCP-violating observables from B±DK±B±DK± and B±Dπ±B±Dπ± decays is presented, where D(D)D(D) is an admixture of D0D0 and ˉD0¯D0 (D0D0 and ˉD0¯D0) states and is reconstructed through the decay chains DDπ0/γDDπ0/γ and DK0Sπ+π/K0SK+KDK0Sπ+π/K0SK+K. The measurement is performed by analysing the signal yield variation across the DD decay phase space and is independent of any amplitude model. [...]

Observation of strangeness enhancement with charmed mesons in high-multiplicity pPbpPb collisions at sNN=8.16sNN=8.16TeV / LHCb Collaboration
The production of promptDs+Ds+ and D+D+ mesons is measured by the LHCb experiment in proton-lead (ppPb) collisions in both the forward (1.5 < yy < 4.0) and backward (-5.0 < yy < -2.5) rapidity regions at a nucleon-nucleon center-of-mass energy of sNNsNN=8.16 TeVTeV. The nuclear modification factors of both Ds+Ds+ and D+D+ mesons are determined as a function of transverse momentum, pTpT, and rapidity. [...]

A search for CP violation in D0K0SK+πD0K0SK+π and D0K0SKπ+D0K0SKπ+ decays is reported. The search is performed using an unbinned model-independent method known as the energy test that probes local CP violation in the phase space of the decays. [...]
