Charmonium production in $p$Ne collisions at $\sqrt{s_{\rm NN}}=68.5$ GeV / LHCb Collaboration
The measurement of charmonium states produced in proton-neon ($p$Ne) collisions by the LHCb experiment in its fixed-target configuration is presented. The production of $J/\psi$ and $\psi(2S)$ mesons is studied with a beam of 2.5 TeV protons colliding on gaseous neon targets at rest, corresponding to a nucleon-nucleon centre-of-mass energy $\sqrt{s_{\rm NN}}=68.5$ GeV.

${{J}/\psi }$ and ${{D}} ^0$ production in $\sqrt{s_{\scriptscriptstyle \text {NN}}} =68.5\,\text {GeV} $ PbNe collisions / LHCb Collaboration
The first measurement of $J/\psi$ and $D^0$ production in PbNe collisions by the LHCb experiment in its fixed-target configuration is reported. The production of $J/\psi$ and $D^0$ mesons is studied with a beam of lead ions with an energy of 2.5 TeV per nucleon colliding on gaseous neon targets at rest, corresponding to a nucleon-nucleon centre-of-mass energy of $\sqrt{s_{\rm NN}}$ = 68.5 GeV.

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..

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. [...]

Readout Firmware of the Vertex Locator for LHCb Run 3 and Beyond / Hennessy, Karol (U. Liverpool (main)) ; Prieto, Antonio Fernandez (Santiago de Compostela U., IGFAE) ; Regueiro, Pablo Vazquez (Santiago de Compostela U., IGFAE) ; Buytaert, Jan (CERN) ; Van Beuzekom, Martin (Nikhef, Amsterdam) ; Cid, Edgar Lemos (Santiago de Compostela U., IGFAE) ; Eklund, Lars (Glasgow U.) ; de Bruyn, Kristof (Nikhef, Amsterdam) ; Naik, Sneha (Glasgow U.) ; Schiller, Manuel (Glasgow U.) et al.
The new LHCb Vertex Locator (VELO) for LHCb, comprising a new pixel detector and readout electronics, will be installed in 2021 for data taking in Run 3 at the LHC. The electronics centers around the “VeloPix” ASIC at the front-end operating in a trigger-less readout at 40MHz. [...]

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).
