 Supplemental figures: $^{3}_{\Lambda}\mathrm{H}$ and $^{3}_{\overline{\Lambda}}\mathrm{\overline{H}}$ lifetime measurement in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} =$ 5.02 TeV via two-body decay /ALICE Collaboration The following note presents supplemental figures for the paper: $^{3}_{\Lambda}\mathrm{H}$ and $^{3}_{\overline{\Lambda}}\mathrm{\overline{H}}$ lifetime measurement in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} =$ 5.02 TeV via two-body decay \cite{Acharya:2019tauh3l}. The (anti-)\hyptriton lifetime has been measured by analyzing the data sample of Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} =$ 5.02 TeV with two methods: the exponential fit to the d$N$/d($ct$) spectrum and the unbinned fit.

 Supplemental figures for measurement of jet radial profiles in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$= 2.76 TeV /ALICE Collaboration This note contains additional figures characterizing the response of jets in a heavy-ion environment measured with the ALICE detector. Via geometrical matching, PYTHIA jets at $\sqrt{s}$ = 2.76 TeV are matched with themselves after embedding into Pb$-$Pb events which were recorded at the same center-of-mass energy in 2011.

 ALICE upgrade physics performance studies for 2018 Report on HL/HE-LHC physics /ALICE Collaboration This document describes the new ALICE performance studies carried out for the CERN Yellow Report of the 2017-2018 HL/HE-LHC Physics Workshop. Studies for light nuclei and hyper-nuclei, flow observables, heavy flavour, quarkonium, low-mass dileptons and photons, jets, Z bosons and photoproduction are presented, for Pb-Pb, p-Pb and pp collisions at high multiplicity [...] ALICE-PUBLIC-2019-001.- Geneva : CERN, 2019 Fulltext: PDF;

 ALICE 2017 luminosity determination for pp collisions at $\sqrt{s}$ = 5 TeV /ALICE Collaboration Luminosity determination in ALICE is based on visible cross sections measured in van der Meer scans. In November 2017, the Large Hadron Collider provided proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 5 TeV. [...] ALICE-PUBLIC-2018-014.- Geneva : CERN, 2018 - 17. Fulltext: PDF;

 Expression of Interest for an ALICE ITS Upgrade in LS3 /ALICE Collaboration Recent innovations in the field of silicon imaging technology for consumer applications open extraordinary opportunities for new detector concepts, and hence offer strongly improved physics scope. This document presents a proposal for the construction of a novel vertex detector consisting of curved wafer-scale ultra-thin silicon sensors arranged in perfectly cylindrical layers, featuring an unprecedented low material budget of 0.05 % $X_{0}$ per layer, with the innermost layer positioned at only 18 mm radial distance from the interaction point.

 Radiation Dose and Fluence in ALICE after LS2 /ALICE Collaboration This note reports radiation calculations referring to the upgraded ALICE detector after the second Long Shutdown (LS2). The simulations are obtained using the FLUKA transport code and take into account the recently measured multiplicities of Pb-Pb, p-Pb and pp collisions.

 Supplemental figures: "Measurement of the inclusive J/$\psi$ polarization at forward rapidity in pp collisions at $\sqrt{s} = 8$ TeV" /ALICE Collaboration This short note presents supplemental figures for the paper "Measurement of the inclusive J/$\psi$ polarization at forward rapidity in pp collisions at $\sqrt{s} = 8$ TeV". The 2-D acceptance and efficiency maps are shown in Fig.1, and the simultaneous fits of the angular distributions of J/$\psi$ reconstructed in the di-muon decay channel (number of J/$\psi$ obtained with the initial setting of the invariant mass fit and corrected for acceptance and efficiency effects) are reported in Fig.2 for the Collins-Soper frame and in Fig.3 for the helicity frame.

 Preliminary Physics Summary: Inclusive $\Upsilon$ production in p-Pb collisions at $\sqrt{s_{\rm NN}} = 8.16$ TeV /ALICE Collaboration The inclusive $\Upsilon$ production in p-Pb interactions at the centre-of-mass energy per nucleon-nucleon collision $\sqrt{s_{\rm NN}} = 8.16$ TeV is studied with the ALICE detector at the CERN LHC. The measurement has been performed reconstructing $\Upsilon$(1S) and $\Upsilon$(2S) mesons via their dimuon decay channel, in the centre-of-mass rapidities $2.03 < y_{\rm cms} < 3.53$ and $-4.46 < y_{\rm cms} < -2.96$, down to zero transverse momentum.
