 Quarkonium projections in p-Pb collisions for Run 3 and Run 4 /ALICE Collaboration This note contains the projections in proton-nucleus collisions for $\psi(2\mathrm{S})/\mathrm{J}/\psi$ and $\Upsilon(n\mathrm{S})/\Upsilon(1\mathrm{S})$ in Run 3 and Run 4. With respect to LHC Run 2, a reduction of a factor $\approx$5 of the statistical uncertainties is estimated, assuming the increase of luminosity from $\sim$21.6 $\mathrm{nb}^{-1}$ to $\sim$500 $\mathrm{nb}^{-1}$..

 Reference pp cross sections for J/$\psi$ and $\psi$(2S) production studies in p--Pb collisions at $\sqrt{s_{\mathrm{NN}}}=8.16$ TeV /ALICE Collaboration The values of the J/$\psi$ and $\psi$(2S) production cross sections in pp collisions at a centre-of-mass energy of $\sqrt{s} = 8.16$ TeV are reported. These values are obtained from the existing measurements at $\sqrt{s} = 8$ TeV using an energy interpolation combined with an extrapolation in rapidity [...] ALICE-PUBLIC-2020-007.- Geneva : CERN, 2020 Fulltext: PDF;

 Physics Preliminary Summary: Measurements of the groomed jet radius and groomed momentum fraction in pp and Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV /ALICE Collaboration We report jet substructure measurements in pp and Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV with the ALICE detector. The groomed jet momentum fraction, $z_\rm{g}$, and the groomed jet radius, $\theta_\rm{g} \equiv R_\rm{g}/R$, are measured using the Soft Drop grooming algorithm.

 Future high-energy pp programme with ALICE /ALICE Collaboration This document presents the proposal of the ALICE Collaboration for an extended data taking programme with high-energy proton-proton collisions ($\sqrt s \approx 13$--14~TeV). The proposed programme includes two components: a sample with a target integrated luminosity of about 200 pb$^{-1}$, for which a highly-selective software-based event skimming will be performed after data reconstruction, and a minimum bias sample with a target integrated luminosity of about 3 pb$^{-1}$.

 Supplemental figures: "First measurement of quarkonium polarization in nuclear collisions at the LHC" /ALICE Collaboration This note contains additional figures accompanying the publication \cite{Acharya:2020xko} in which the first measurement of quarkonium polarization in heavy-ion collisions is discussed.

 Supplemental figures: "Transverse-momentum and event-shape dependence of D-meson flow harmonics in Pb-Pb collisions at ${\sqrt{s_{\rm{NN}}} = 5.02}$ TeV" /ALICE Collaboration The following public note presents supplemental figures for the paper "Transverse-momentum and event-shape dependence of D-meson flow harmonics in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}} = 5.02$ TeV"~\cite{Acharya:2020pnh}. The elliptic ($v_2$) and triangular ($v_3$) flow coefficients of prompt non-strange D mesons were measured at midrapidity ($|y|<0.8$) in the transverse momentum interval $1< p_{\rm T} <36$ GeV/$c$ in central (0-10\%) and semi-central (30-50\%) Pb-Pb collisions at the centre-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}}$=5.02 TeV with the ALICE detector at the LHC.

 Groomed jet substructure measurements of charm jets tagged with $\rm{D}^{0}$ mesons in pp collisions at $\sqrt{s}$ = 13 TeV /ALICE Collaboration The ALICE collaboration at the CERN LHC reports the first measurements of groomed jet substructure observables for jets containing a fully reconstructed $\rm{D}^{0}$ in pp collisions at $\sqrt{s}$ = 13 TeV. Iterative declustering techniques access the jet splitting tree of track-based jets, with grooming techniques isolating the perturbative branches.

 Data-driven model for the emission of spectator nucleons as a function of centrality in Pb-Pb collisions at LHC energies /ALICE Collaboration At colliders the Zero Degree Carimeters (ZDC) measure mainly the energy carried by free'' spectators, namely the fragments are not bound in fragments after the collision. The most commonly used event generators for nucleus-nucleus collisions do not include a reliable model to describe the formation of nuclear fragments.

 A Forward Calorimeter (FoCal) in the ALICE experiment /ALICE Collaboration We discuss a forward electromagnetic and hadronic calorimeter (FoCal) as a possible upgrade to the ALICE experiment, which could be installed during LS3 for data-taking in 2026–2028 at the LHC. The FoCal is a highly granular Si+W electromagnetic calorimeter combined with a conventional sampling hadronic calorimeter covering pseudorapidities of 3.2 < $\eta$ < 5.8.
