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.

Preliminary Physics Summary: Transverse momentum and centrality dependence of inclusive J/$\psi$ production in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV /ALICE Collaboration
Inclusive J/$\psi$ production in minimum bias p-Pb collisions at a collision energy per nucleon–nucleon pair of $\sqrt{s_{\rm NN}} = 5.02$ TeV is studied with a recent dataset from 2016 recorded by ALICE at the CERN-LHC. The production of J/$\psi$ is investigated in the dielectron channel in the central barrel in the centre-of-mass rapidity interval of $-1.37 < y_{\rm cms} < 0.43$. [...]

Preliminary Physics Summary: Measurement of D$^0$, D$^+$, D$^{*+}$ and D$_{\rm s}^+$ production in pp collisions at $\sqrt{s}= 5.02$ TeV with ALICE /ALICE Collaboration
The preliminary measurement of the production of prompt D$^0$, D$^+$, D$^{*+}$ and D$_{\rm s}^+$ mesons in proton-proton collisions at $\sqrt{s}= 5.02$ TeV with the ALICE detector at the LHC is reported. D mesons were reconstructed at mid-rapidity via their hadronic decay channels ${\rm D}^0\rightarrow {\rm K}^-\pi^+$, ${\rm D}^+\rightarrow {\rm K}^-\pi^+\pi^+$, ${\rm D}^{*+}\rightarrow {\rm D}^0\pi^+$, ${\rm D}_s^+\rightarrow \phi\pi^+\rightarrow {\rm K}^+{\rm K}^-\pi^+$, and their charge conjugates.

Preliminary Physics Summary: Measurements of low-$p_{\rm T}$ electrons from semileptonic heavy-flavour hadron decays at mid-rapidity in pp collisions at $\sqrt{s}= 7$ TeV /ALICE Collaboration
The transverse-momentum ($p_{\rm T}$) differential production cross section of electrons from semileptonic heavy-flavour hadron decays has been measured in the interval $0.5 < p_{\rm T} < 4.0$ GeV/$c$ at mid-rapidity ($|y| < 0.8$) in proton-proton collisions at $\sqrt{s} = 7$ TeV with ALICE at the LHC. Statistical and systematic uncertainties have been reduced by a factor of about three with respect to previously published results. [...]

Production of $\omega(782)$ in pp collisions at $\sqrt{s}$ = 7 TeV /ALICE Collaboration
The production of $\omega(782)$meson has been measured at mid-rapidity in pp collisions at $\sqrt{s}$ = 7 TeV with the ALICE detector at the Large Hadron Collider (LHC). The particles are reconstructed in the $\omega\rightarrow\pi^{0}\pi^{+}\pi^{-}$ decay channel. [...]

Centrality determination using the Glauber model in Xe-Xe collisions at $\sqrt{s_{\rm NN}} = 5.44$ TeV /ALICE Collaboration
This document describes the methods used by the ALICE Collaboration for determining the centrality of Xe-Xe collisions at $\sqrt{s_{\rm NN}} = 5.44$ TeV at the LHC within the Glauber model. The half-density radius $R$ and the diffusivity $a$ describing the Xe-129 nucleus with a 2-parameter Fermi distribution have been derived from a recent electron scattering measurement for the Xe-132 nucleus.

ALICE luminosity determination for p-Pb collisions at $\sqrt{s_{\rm NN}}=8.16$ TeV /ALICE Collaboration
Luminosity determination in ALICE is based on visible cross sections measured in van der Meer scans. In 2016, the Large Hadron Collider provided proton-lead collisions at a centre-of-mass energy of $\sqrt{s_{\rm NN}}=8.16$ TeV [...]
