Observation of new Ωc0 states decaying to the Ξc+K final state / LHCb Collaboration
Two new excited states, Ωc(3185)0 and Ωc(3327)0, are observed in the Ξc+K invariant-mass spectrum using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9fb1. Five previously observed excited Ωc0 states are confirmed, namely Ωc(3000)0, Ωc(3050)0, Ωc(3065)0, Ωc(3090)0, and Ωc(3119)0. [...]

Model-independent measurement of charm mixing parameters in B¯D0(KS0π+π)μν¯μX decays / LHCb Collaboration
A measurement of charm mixing and CP-violating parameters is reported, using B¯D0(KS0π+π)μν¯μX decays reconstructed in proton-proton collisions collected by the LHCb experiment during the years 2016 to 2018, corresponding to an integrated luminosity of 5.4 fb1. The measured mixing and CP-violating parameters are xCP=[4.29±1.48(stat)±0.26(syst)]×103, yCP=[12.61±3.12(stat)±0.83(syst)]×103, Δx=[0.77±0.93(stat)±0.28(syst)]×103, Δy=[3.01±1.92(stat)±0.26(syst)]×103. The results are complementary to and consistent with previous measurements. [...]

Measurement of the prompt D0 nuclear modification factor in pPb collisions at sNN=8.16 TeV / LHCb Collaboration
The production of prompt D0 mesons in proton-lead collisions in the forward and backward configurations at a center-of-mass energy per nucleon pair of sNN=8.16 TeV is measured by the LHCb experiment. The nuclear modification factor of prompt D0 mesons is determined as a function of the transverse momentum pT, and rapidity in the nucleon-nucleon center-of-mass frame y. [...]

Search for CP violation using T^-odd correlations in B0pp¯K+π decays / LHCb Collaboration
A search for CP and P violation in charmless four-body B0pp¯K+π decays is performed using triple-product asymmetry observables. It is based on 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 8.4 fb1. [...]

Nuclear modification factor of neutral pions in the forward and backward regions in pPb collisions / LHCb Collaboration
The nuclear modification factor of neutral pions is measured in proton-lead collisions collected at a center-of-mass energy per nucleon of 8.16 TeV with the LHCb detector. The π0 production cross section is measured differentially in transverse momentum (pT) for 1.5<pT<10.0 GeV and in center-of-mass pseudorapidity (ηCM) regions 2.5<ηCM<3.5 (forward) and 4.0<ηCM<3.0 (backward) defined relative to the proton beam direction.

Search for the rare hadronic decay Bs0pp¯ / LHCb Collaboration
A search for the rare hadronic decay Bs0pp¯ is performed using proton-proton collision data recorded by the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 6 fb1. No evidence of the decay is found and an upper limit on its branching fraction is set at B(Bs0pp¯)<4.4 (5.1)×109 at 90% (95%) confidence level; this is currently the world's best upper limit. [...]
