The polarization of Λ and ˉΛ hyperons along the beam direction has been measured relative to the second and third harmonic event planes in isobar Ru+Ru and Zr+Zr collisions at sNN = 200 GeV. This is the first experimental evidence of the hyperon polarization by the triangular flow originating from the initial density fluctuations. [...]

First branching fraction measurement of the suppressed decay Ξ0cπΛ+c / LHCb Collaboration
The Ξ0c baryon is unstable and usually decays into charmless final states by the csu¯d transition. It can, however, also disintegrate into a π meson and a Λ+c baryon via s quark decay or via csdc weak scattering. [...]

First observation of the decay Λ0bηc(1S)pK / LHCb Collaboration
The decay Λ0bηc(1S)pK is observed for the first time using a data sample of proton-proton collisions, corresponding to an integrated luminosity of 5.5 fb1, collected with the LHCb experiment at a centre-of-mass energy of 13 TeV. The branching fraction of the decay is measured, using the Λ0bJ/ψpK decay as a normalisation mode, to be B(Λ0bηc(1S)pK)=(1.06±0.16±0.06+0.220.19)×104, where the quoted uncertainties are statistical, systematic and due to external inputs, respectively.

Observation of enhanced double parton scattering in proton-lead collisions at sNN=8.16 TeV / LHCb Collaboration
A study of prompt charm-hadron pair production in proton-lead collisions at sNN=8.16 TeV is performed using data corresponding to an integrated luminosity of about 30 nb1, collected with the LHCb experiment. Production cross-sections for different pairs of charm hadrons are measured and kinematic correlations between the two charm hadrons are investigated. [...]

The first observation of the decay B0D0¯D0K+π is reported using proton-proton collision data corresponding to an integrated luminosity of 4.7 fb1 collected by the LHCb experiment in 2011, 2012 and 2016. The measurement is performed in the full kinematically allowed range of the decay outside of the D region. [...]

Searches for low-mass dimuon resonances / LHCb Collaboration
Searches are performed for low-mass dimuon resonances, X, produced in proton-proton collisions at a center-of-mass energy of 13 TeV, using a data sample corresponding to an integrated luminosity of 5.1 fb1 and collected with the LHCb detector. The Xμ+μ decays can be either prompt-like or displaced from the proton-proton collision, where in both cases the requirements placed on the event and the assumptions made about the production mechanisms are kept as minimal as possible.

Observation of structure in the J/ψ-pair mass spectrum / LHCb Collaboration
Using proton-proton collision data at centre-of-mass energies of s=7, 8 and 13TeV recorded by the LHCb experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 9fb1, the invariant mass spectrum of J/ψ pairs is studied. A narrow structure around 6.9GeV/c2 matching the lineshape of a resonance and a broad structure just above twice the J/ψ mass are observed. [...]

Search for CP violation in Ξ+cpKπ+ decays using model-independent techniques / LHCb Collaboration
A first search for CP violation in the Cabibbo-suppressed Ξ+cpKπ+ decay is performed using both a binned and an unbinned model-independent technique in the Dalitz plot. The studies are based on a sample of proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb1, and collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV.
