Momentum transformation matrix for dielectron simulations in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=2.76\ \mathrm{TeV}$ /ALICE Collaboration
The measured invariant mass spectrum of dielectron pairs is affected by the finite momentum resolution of the detector, the energy loss of electrons and positrons in the detector material, and the tracking procedure. The unfolding of detector effects cannot be performed in multiple dimensions (invariant mass, pair-$p_{\mathrm{T}}$) simultaneously since $N$-dimensional detector response matrices with $N = 4$ would be required, for which an algebra cannot be defined.

Supplemental material: afterburner for generating light (anti-)nuclei with QCD-inspired event generators in pp collisions /ALICE Collaboration
This note complements the paper titled: ``Production of deuterons, tritons, $^{3}$He nuclei and their anti-nuclei in pp collisions at $\sqrt{s}$~=~0.9, 2.76 and 7~TeV'' with additional material related to Monte Carlo simulations necessary to compare the results with lower energy experiments. It describes a coalescence-based afterburner for QCD-inspired event generators, which allows the generation of light nuclei, hyper-nuclei and their charge conjugates in proton--proton (pp) collisions at LHC energies.

Supplemental figures: $\pi^{0}$ and $\eta$ meson production in proton-proton collisions at $\sqrt{s}=8$ TeV /ALICE Collaboration
This note provides supplemental figures for the paper ``$\pi^{0}$ and $\eta$ meson production in proton-proton collisions at $\sqrt{s}=8$ TeV''. The set of example plots for both neutral mesons showing the invariant mass distributions for each reconstruction method for all calorimeter triggers used in analysis is completed. [...]

Preliminary Physics Summary: Measurement of prompt $D^0$, $D^+$, $D^{*+}$ and $D_s^+$ production in p-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV /ALICE Collaboration
We report preliminary measurements of the production of prompt $D^0$, $D^+$, $D^{*+}$ and $D_s^+$ mesons in p-Pb collisions at the centre-of-mass energy $\sqrt{s_{\rm NN}}=5.02$ TeV per nucleon-nucleon collision. The production yields are measured at mid-rapidity ($-$0.96$<$$y_{\rm cms}$$<$0.04) as a function of transverse momentum ($p_{\rm T}$) in the intervals 0$<$$p_{\rm T}$$<$36 GeV/$c$ for $D^0$, 1$<$$p_{\rm T}$$<$36 GeV/$c$ for $D^+$ and $D^{*+}$, and 2$<$$p_{\rm T}$$<$24 GeV/$c$ for $D_s^+$ mesons.

Preliminary Physics Summary: Centrality dependence of inclusive J/$\psi$ production in p-Pb collisions at $\sqrt{s_{\rm NN}}=8.16$ TeV /ALICE Collaboration
The inclusive J/$\psi$ 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 J/$\psi$ 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.

Preliminary Physics Summary: Deuteron and anti-deuteron production in pp collisions at $\sqrt{s}=13$ TeV and in Pb–Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV /ALICE Collaboration
The mechanism which is behind the production of light (anti–)nuclei in ultra-relativistic collisions is one of the open questions in high-energy physics. We present the preliminary results obtained from the analyses of the (anti-)deuteron production for two different data samples collected in the LHC run 2: pp collisions at $\sqrt{s}=13$ TeV and Pb–Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV.

The ALICE definition of primary particles /ALICE Collaboration
In this public note, we specify what we mean by the term ``primary particle''. The definition is motivated by what is in principle measurable by ALICE and that event generators and other such theoretical considerations must be able to reproduce the same requirements [...]

We report preliminary measurements of the production of prompt D$^0$, D$^+$, D$^{*+}$ and D$_{\rm s}^+$ mesons in Pb-Pb collisions in the centrality classes 0-10%, 30-50% and 60-80%, at the centre-of-mass energy $\sqrt{s_{\rm NN}}=5.02$ TeV per nucleon-nucleon collision. The production yields are measured at mid-rapidity ($|y|<0.5$) as a function of transverse momentum ($p_{\rm T}$) [...]

ALICE luminosity determination for pp collisions at $\sqrt{s}=8$ TeV /ALICE Collaboration
Luminosity determination in ALICE is based on visible cross sections measured in van der Meer scans. In 2012, the Large Hadron Collider provided proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=8$ TeV. [...]
