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.

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 [...]

Measurement of the angle between jet axes in pp collisions at $\sqrt{s}=5.02$ TeV / ALICE Collaboration, CERN
This article reports measurements of the angle between differently defined jet axes in pp collisions at $\sqrt{s} = 5.02$ TeV carried out by the ALICE Collaboration. Charged particles at midrapidity are clustered into jets with resolution parameters $R=0.2$ and 0.4. [...]

Measurement of electrons from beauty-hadron decays in pp and Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV / ALICE Collaboration, CERN /ALICE
The production of electrons from beauty-hadron decays was measured at midrapidity in proton-proton (pp) and central Pb-Pb collisions at center-of-mass energy per nucleon-nucleon pair $\sqrt{s_{\rm NN}}$ = 5.02 TeV, using the ALICE detector at the LHC. The cross section measured in pp collisions in the transverse momentum interval $2 < p_{\rm T} < 8$ GeV/$c$ was compared with models based on perturbative quantum chromodynamics calculations [...]

Two-particle transverse momentum correlations in pp and p-Pb collisions at LHC energies / ALICE Collaboration, CERN /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. The longitudinal long-range correlations and the large azimuthal anisotropy measured at low transverse momenta in small collision systems, namely pp and p-Pb, at LHC energies resemble manifestations of collective behaviour.

The ALICE experiment - A journey through QCD / ALICE Collaboration, CERN /ALICE
The ALICE experiment was proposed in 1993, to study strongly interacting matter at extreme energy densities via a comprehensive investigation of nuclear collisions at the LHC. Its physics programme initially focused on the determination of the properties of the Quark-Gluon Plasma (QGP), a deconfined state of quarks and gluons and was extended along the years, covering a diverse ensemble of observables related to Quantum Chromodynamics (QCD), the theory of strong interactions.

Jet-like correlations with respect to ${\rm K}^{0}_{\rm{S}}$ and $\Lambda$($\overline{\Lambda}$) in pp and Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV} /ALICE Collaboration
Two-particle correlations with ${\rm K}^{0}_{\rm{S}}$, $\Lambda$/$\overline{\Lambda}$, and charged hadrons as trigger particles in the transverse momentum range $8 < p_\mathrm{T,trig}<16$ GeV/$c$, and associated charged particles within $1 < p_\mathrm{T,assoc}<8$ GeV/$c$, are studied at mid-rapidity in pp and central Pb-Pb collisions at a centre-of-mass energy per nucleon-nucleon collision $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV with the ALICE detector at the LHC. After subtracting the contributions of the flow background, the per-trigger yields are extracted on both the near and away sides, and the ratio in Pb-Pb collisions with respect to pp collisions ($I_{\mathrm {AA}}$) is computed.

Search for the Chiral Magnetic Effect with charge-dependent azimuthal correlations in Xe-Xe collisions at $\sqrt{s_{\mathrm{NN}}} = 5.44$ TeV /ALICE Collaboration
Charge-dependent two- and three-particle correlations measured in Xe-Xe collisions at $\sqrt{s_{\mathrm{NN}}} = 5.44$ TeV are presented. Results are obtained for charged particles in the pseudorapidity range $|\eta|<0.8$ and transverse momentum interval $0.2 \le p_{\rm T}<5.0$ GeV/$c$ for different collision centralities. [...]

Production of ${\rm K}^{0}_{\rm{S}}$, $\Lambda$ ($\overline{\Lambda}$), $\Xi^{\pm}$ and $\Omega^{\pm}$ in jets and in the underlying event in pp and p$-$Pb collisions / ALICE Collaboration, CERN
The production of strange hadrons (${\rm K}^{0}_{\rm{S}}$, ${\Lambda}$, $\Xi^{\pm}$, 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. The inclusive production of the same particle species and the corresponding ratios are also reported. [...]
