 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 [...] LHCB-FIGURE-2019-020.- Geneva : CERN, 2019 - 8.

 $\mathcal{Xc1} (3872)$ production in $p\rm{Pb}$ and $\rm{Pb}$$p collisions at \sqrt{sNN} = 8.16 TeV /LHCb Collaboration This document shows performance plots of the J/\psi \ \pi^+\pi^- invariant mass spectra from p\rm{Pb} and \rm{Pb}$$p$ collisions at $\sqrt{sNN}$ = 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 $\mathcal{Xc1} (3872)$ 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.

 Performance of a multithreaded prototype for the future LHCb simulation framework (Gauss-on-Gaussino) /LHCb Collaboration We present performance plots for a prototype of a upcoming version of LHCb’s simulation framework Gauss. This prototype of Gauss is multithreaded and built on Gaussino and incorporates the LHCb speciﬁc features necessary to create simulated samples with LHCb conditions..
