Throughput scaling of the Hlt1 track reconstruction on many CPU core machines /LHCb Collaboration
The Hlt1 throughput scaling on CPUs with up to 64 physical cores is shown. We demonstrate that the Hlt1 software exhibits an almost linear scaling up to the number of physical cores..

Publicity plots approval: Charm production in PbPb collisions at $\sqrt{s_{NN}}$ = 5 TeV and in $p$Pb collisions at $\sqrt{s_{NN}}$= 8 TeV /LHCb Collaboration
This document presents performance plots for the full PbPb dataset at $\sqrt{s_{\rm NN}}$ = 5 TeV recorded in 2018 by the LHCb Collaboration as well as new performance plots in $p$Pb collisions at $\sqrt{s_{\rm NN}}$ = 8.16 TeV. For the first dataset, a fit of the open-charm mesons $D$, $D^+_s$, $D^+$, the charm baryon $\Lambda^+_c$ and the charmonium $J/\psi$ are shown [...]

$\mathcal{Xc1} (3872)$ production in $p\rm{Pb}$ and $\rm{Pb}$$p$ collisions at $\sqrt{sNN}$ = 8.16 TeV /LHCb Collaboration
This document shows performance plots of the $J/\psi\pi^{+}\pi^{-}$ invariant mass spectra from $p$Pb and Pb$p$ collisions at $\sqrt{s_{NN}}$ = 8.16 TeV, to be shown at the conference Quark Matter 2019. Once combined with appropriate efficiency corrections, this data can be used to place limits on the nuclear modification factor of the exotic $\chi_{c1}$(3872) state [...]

2018 Alignment stability plots /LHCb Collaboration
In Run 2, a new scheme for the software trigger at LHCb allowed splitting the triggering of events in two stages, giving room to perform the detector alignment and calibration in real time. In the detector alignment and calibration strategy for Run 2, data collected at the start of the fill are processed in a few minutes and used to update the alignment constants, while the calibration constants are evaluated for each run. [...]

Comparison of the decay time resolution in Run 1 and Run 2 /LHCb Collaboration
In this document, the $B_s^0$ decay time resolution in the decay $B_s^0 \to J/\psi \phi$ at the LHCb experiment is presented. The time resolution is evaluated as a function of the $B_s^0$ momentum and estimated decay time error. [...]
