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.

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. [...]

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.
