First measurement of $Z \to \mu^+\mu^-$ angular coefficients in the forward region of $pp$ collisions at $\sqrt{s} = 13$ TeV / LHCb Collaboration
The first study of the angular distribution of $\mu^+ \mu^-$ pairs produced in the forward rapidity region via the Drell-Yan reaction $pp \rightarrow \gamma^{*}/Z +X \rightarrow l^+ l^- + X$ is presented, using data collected with the LHCb detector at a centre-of-mass energy of 13TeV, corresponding to an integrated luminosity of 5.1 $\rm{fb}^{-1}$. The coefficients of the five leading terms in the angular distribution are determined as a function of the dimuon transverse momentum and rapidity. [...]

Measurement of $\tau _\text {L}$ using the ${B} _s^0 \rightarrow J/\psi \eta $ decay mode / LHCb Collaboration
Using a proton-proton collision data sample collected by the LHCb detector and corresponding to an integrated luminosity of 5.7 $\text{fb}^{-1}$, the lifetime of the $B_{s}^{0}$ mass eigenstate, $\tau_{L}$, is measured using $B_{s}^{0} \to J/\psi \eta$ decay mode to be $\tau_{L}$ = 1.445 $\pm$ 0.016(stat) $\pm$ 0.008(syst) ps. A combination of this result with a previous LHCb analysis using an independent dataset corresponding to 3 $\text{fb}^{-1}$ of integrated luminosity gives $\tau_{L}$ = 1.452 $\pm$ 0.014 $\pm$ 0.007 $\pm$ 0.002 ps, where the first uncertainty is statistical, the second due to the uncorrelated part of the systematic uncertainty and the third due to the correlated part of the systematic uncertainty..

Measurement of antiproton production from antihyperon decays in pHe collisions at $\sqrt{s_{NN}}=110$ GeVMeasurement of antiproton production from antihyperon decays in ${p} \textrm{He}$ collisions at $\sqrt{s_{\scriptscriptstyle \mathrm NN}} =110\,\text {Ge\hspace{-1.00006pt}V}$ / LHCb Collaboration
The interpretation of cosmic antiproton flux measurements from space-borne experiments is currently limited by the knowledge of the antiproton production cross-section in collisions between primary cosmic rays and the interstellar medium. Using collisions of protons with an energy of 6.5 TeV incident on helium nuclei at rest in the proximity of the interaction region of the LHCb experiment, the ratio of antiprotons originating from antihyperon decays to prompt production is measured for antiproton momenta between 12 and 110 GeV/c.

Searches for rare $ {B}_s^0 $ and B$^{0}$ decays into four muons / LHCb Collaboration
Searches for rare $B_s^0$ and $B^0$ decays into four muons are performed using proton-proton collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 9 $\text{fb}^{-1}$. Direct decays and decays via light scalar and $J/\psi$ resonances are considered. [...]

Measurement of $J/\psi$ production cross-sections in $pp$ collisions at $\sqrt{s}=5$ TeV / LHCb Collaboration
The production cross-sections of $J/\psi$ mesons in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=5$ TeV are measured using a data sample corresponding to an integrated luminosity of $9.13\pm0.18~\text{pb}^{-1}$, collected by the LHCb experiment. The cross-sections are measured differentially as a function of transverse momentum, $p_{\text{T}}$, and rapidity, $y$, and separately for $J/\psi$ mesons produced promptly and from beauty hadron decays (nonprompt).
