Light (anti)nuclei production in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV / ALICE Collaboration, CERN /ALICE
The measurement of the production of deuterons, tritons and ${^{3}\mathrm{He}}$ and their antiparticles in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV is presented in this article. The measurements are carried out at midrapidity ($|y| < 0.5$) as a function of collision centrality using the ALICE detector. [...]

First measurement of $\mathbf{\Lambda}_\mathbf{c}^\mathbf{+}$ production down to $p_\mathbf{T} = \mathbf{0}$ in pp and p-Pb collisions at $\sqrt{s_\mathbf{NN}}= \mathbf{5.02 TeV}$ / ALICE Collaboration, CERN
The production of prompt ${\mathrm {\Lambda_{c}^{+}}}$ baryons has been measured at midrapidity in the transverse momentum interval $0 < p_{\rm T} < 1$ GeV/$c$ for the first time, in pp and p-Pb collisions at a centre-of-mass energy per nucleon-nucleon collision $\sqrt{s_\mathrm{NN}} = 5.02$ TeV. The measurement was performed in the decay channel $\mathrm{\rm \Lambda_{c}^{+} \to p K^{0}_{S}}$ by applying new decay reconstruction techniques using a Kalman-Filter vertexing algorithm and adopting a machine-learning approach for the candidate selection.

Two-particle transverse momentum correlations in pp and p-Pb collisions at LHC energies / Collaboration, Alice
Two-particle transverse momentum differential correlators, recently measured in Pb-Pb collisions at LHC energies, provide an additional tool to gain insights into particle production mechanisms and infer transport properties, such as the ratio of shear viscosity to entropy density, of the medium created in Pb-Pb collisions.

Production of ${\rm K}^{0}_{\rm{S}}$, $\Lambda$ ($\bar{\Lambda}$), $\Xi^{\pm}$ and $\Omega^{\pm}$ in jets and in the underlying event in pp and p$-$Pb collisions
The production of strange hadrons (K$^{0}_{\rm S}$, $\Lambda$, $\Xi^{\pm}$, and $\Omega^{\pm}$), baryon-to-meson ratios ($\Lambda/{\rm K}^{0}_{\rm S}$, $\Xi/{\rm K}^{0}_{\rm S }$, and $\Omega/{\rm K}^{0}_{\rm S}$), and baryon-to-baryon ratios ($\Xi/\Lambda$, $\Omega/\Lambda$, and $\Omega/\Xi$) associated with jets and the underlying event were measured as a function of transverse momentum ($p_{\rm T}$) in pp collisions at $\sqrt{s} = 13$ TeV and p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV with the ALICE detector at the LHC.

J/$\psi$ production at midrapidity in p$-$Pb collisions at $\sqrt{s_{NN}} = 8.16$ TeV / ALICE Collaboration, CERN /ALICE
The production of inclusive, prompt and non-prompt J/$\psi$ was studied for the first time at midrapidity ($ -1.37 < y_{\rm cms} < 0.43$) in p$-$Pb collisions at $\sqrt{s_{\rm NN}} = 8.16$ TeV with the ALICE detector at the LHC. The inclusive J/$\psi$ mesons were reconstructed in the dielectron decay channel in the transverse momentum ($p_{\rm T}$) interval $0 < p_{\rm T} < 14$ \GeVc and the prompt and non-prompt contributions were separated on a statistical basis for $p_{\rm T} > 2$ \GeVc [...]

System-size dependence of particle production at mid- and forward rapidity with ALICE / Modak, Abhi (CAPSS, Kolkata)
The pseudorapidity densities of charged particles and inclusive photons produced in high energy nuclear collisions are essential observables to characterise the global properties of the collisions, such as the achieved energy density, and to provide important constraints for Monte Carlo model calculations.
