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. [...]

Second order event plane dependence of jet-hadron correlations in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV /ALICE Collaboration
In the paper linked to this note, we reported the yields, yield differences, yield ratios, widths of jet-hadron correlations relative to the reaction plane in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV for reconstructed jet transverse momenta 20 < $p_{\rm{T}}^{\rm{jet}}$ < 40 GeV/$c$ as a function of the angle between the reconstructed jet and the reaction plane. A sample correlation function was shown in the paper for associated particles with momenta 20 < $p_{\rm{T}}^{\rm{assoc}}$ < 40 GeV/$c$. [...]

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.
