Inclusive $\text {J}/\psi $ production at midrapidity in pp collisions at $\sqrt{s} = 13$ TeV / ALICE Collaboration
We report on the inclusive J/ψ production cross section measured at the CERN Large Hadron Collider in proton–proton collisions at a centre-of-mass energy s = 13 TeV. The J/ψ mesons are reconstructed in the e+e− decay channel and the measurements are performed at midrapidity (|y| < 0.9) in the transverse-momentum interval 0 < pT < 40 GeV/c, using a minimum-bias data sample corresponding to an integrated luminosity Lint = 32.2 nb−1 and an Electromagnetic Calorimeter triggered data sample with Lint = 8.3 pb−1.

Prompt and non-prompt J/ψ production cross sections at midrapidity in proton-proton collisions at $ \sqrt{\mathrm{s}} $ = 5.02 and 13 TeV / ALICE Collaboration
The production of J/$\psi$ is measured at midrapidity ($|y|<0.9$) in proton-proton collisions at $\sqrt{s}$ = 5.02 and 13 TeV, through the dielectron decay channel, using the ALICE detector at the Large Hadron Collider. The data sets used for the analyses correspond to integrated luminosities of \mbox{$\mathcal{L}_{\rm int}$ = 19.4$\pm$0.4~nb$^{-1}$} and \mbox{ $\mathcal{L}_{\rm int}$ = 32.3$\pm$1.6~nb$^{-1}$} at $\sqrt{s}$ = 5.02 and 13 TeV, respectively.

Measurement of the groomed jet radius and momentum splitting fraction in pp and Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV / ALICE Collaboration
This article presents groomed jet substructure measurements in pp and Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV with the ALICE detector. The Soft Drop grooming algorithm provides access to the hard parton splittings inside a jet by removing soft wide-angle radiation. [...]

Anisotropic flow of identified hadrons in Xe-Xe collisions at $ \sqrt{s_{\mathrm{NN}}} $ = 5.44 TeV / ALICE Collaboration
Measurements of elliptic ($v_{2}$) and triangular ($v_{3}$) flow coefficients of $\pi^{\pm}$, K$^{\pm}$, p+$\overline{\rm p}$, K$^{0}_{S}$, and $\Lambda$+$\overline{\Lambda}$ obtained with the scalar product method in Xe$-$Xe collisions at $\sqrt{s_{\rm NN}} = 5.44$ TeV are presented. The results are obtained in the rapidity range |y| < 0.5 and reported as a function of transverse momentum, $p_{\rm T}$, for several collision centrality classes. [...]

Polarization of $\Lambda$ and $\overline{\Lambda}$ hyperons along the beam direction in Pb–Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst. Inform.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
The polarization of the $\Lambda$ and $\overline{\Lambda}$ hyperons along the beam ($z$) direction, $P_{z}$, has been measured in Pb–Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV recorded with ALICE at the Large Hadron Collider (LHC). The largest contribution to $P_z$ comes from elliptic flow induced vorticity and can be characterized by the second Fourier sine coefficient $P_{z,s2}$ = $⟨P_z sin(2 \varphi − 2 \Psi_2 )⟩$, where $\varphi$ is the hyperon azimuthal emission angle, and $\Psi_2$ is the elliptic flow plane angle.

K$^{0}_{\rm S}$- and (anti-)$\Lambda$-hadron correlations in pp collisions at $\sqrt{s} = 13$ TeV / ALICE Collaboration
Two-particle azimuthal correlations are measured with the ALICE apparatus in pp collisions at $\sqrt{s} = 13$ TeV to explore strangeness- and multiplicity-related effects in the fragmentation of jets and the transition regime between bulk and hard production, probed with the condition that a strange meson (K$^{0}_{\rm S}$) or a baryon ($\Lambda$) with transverse momentum $p_{\rm T} > 3$ GeV/c is produced. Azimuthal correlations between kaons or $\Lambda$ hyperons with other hadrons are presented at midrapidity for a broad range of the trigger ($3 < p_{\rm T}^{\rm trigg} < 20$ GeV/$c$) and associated particle $p_{\rm T}$ (1 GeV/$c$ $< p_{\rm T}^{\rm assoc} < p_{\rm T}^{\rm trigg}$), for minimum-bias events and as a function of the event multiplicity.

Measurements of the groomed and ungroomed jet angularities in pp collisions at $\sqrt{s} = 5.02$ TeV / ALICE Collaboration
The jet angularities are a class of jet substructure observables which characterize the angular and momentum distribution of particles within jets. These observables are sensitive to momentum scales ranging from perturbative hard scatterings to nonperturbative fragmentation into final-state hadrons. [...]

Study of very forward energy and its correlation with particle production at midrapidity in pp and p-Pb collisions at the LHC / ALICE Collaboration
The very forward energy is a powerful tool for characterising the proton fragmentation in pp and p-Pb collisions and, studied in correlation with particle production at midrapidity, provides direct insights into the initial stages and the subsequent evolution of the collision. Furthermore, the correlation between the forward energy and the production of particles with large transverse momenta at midrapidity provides information complementary to the measurements of the underlying event, which are usually interpreted in the framework of models implementing centrality-dependent multiple parton interaction.

Hypertriton Production in p-Pb Collisions at $\sqrt {s_{NN}}$=5.02 TeV / ALICE Collaboration
The study of nuclei and antinuclei production has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic collisions. The first measurement of the production of ${\rm ^{3}_{\Lambda}\rm H}$ in p-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV is presented in this Letter. [...]

Direct observation of the dead-cone effect in quantum chromodynamics / ALICE Collaboration
At particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of quantum chromodynamics (QCD) [1]. The vacuum is not transparent to the partons and induces gluon radiation and quark pair production in a process that can be described as a parton shower [2]. [...]
