First study of the two-body scattering involving charm hadrons / ALICE Collaboration
This Letter presents the first measurement of the interaction between charm hadrons and nucleons. The two-particle momentum correlations of $\mathrm{pD}^{−}$ and $\overline{\mathrm{p}}\mathrm{D}^{+}$ pairs are measured by the ALICE Collaboration in high-multiplicity pp collisions at $\sqrt{s} = 13$ TeV. [...]

Study of flavor dependence of the baryon-to-meson ratio in proton-proton collisions at $\sqrt{s}$ = 13 TeV / ALICE Collaboration
The production cross sections of ${\rm D^0}$ and $\Lambda^+_{\rm c}$ hadrons originating from beauty-hadron decays (i.e. non-prompt) were measured for the first time at midrapidity ($|y|<0.5$) by the ALICE Collaboration in proton-proton collisions at a center-of-mass energy $\sqrt{s}=13$ TeV. [...]

Measurements of Chemical Potentials in Pb–Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV / ALICE Collaboration
This Letter presents the most precise measurement to date of the matter/antimatter imbalance at midrapidity in Pb–Pb collisions at a center-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}} = 5.02$ TeV. Using the Statistical Hadronization framework, it is possible to obtain the value of the electric charge and baryon chemical potentials, $\mu_{\rm Q} = −0.18 \pm 0.90$ MeV and $\mu_{\rm B} = 0.71 \pm 0.45$ MeV, with unprecedented precision.

Emergence of Long-Range Angular Correlations in Low-Multiplicity Proton-Proton Collisions / ALICE Collaboration
This Letter presents the measurement of near-side associated per-trigger yields, denoted ridge yields, from the analysis of angular correlations of charged hadrons in proton--proton collisions at $\sqrt{s}$ = 13 TeV. Long-range ridge yields are extracted for pairs of charged particles with a pseudorapidity difference of $1.4 < |\Delta\eta| < 1.8$ and a transverse momentum of $1 < p_{\rm T} < 2$ GeV/$c$, as a function of the charged-particle multiplicity measured at mid-rapidity. [...]

Photoproduction of ${\rm K}^{+} {\rm K}^{−}$ Pairs in Ultraperipheral Collisions / ALICE Collaboration
${\rm K}^{+} {\rm K}^{−}$ pairs may be produced in photonuclear collisions, either from the decays of photoproduced $\phi (1020)$ mesons, or directly as non-resonant ${\rm K}^{+} {\rm K}^{−}$ pairs. Measurements of ${\rm K}^{+} {\rm K}^{−}$ photoproduction probe the couplings between the $\phi (1020)$ and charged kaons with photons and nuclear targets. [...]

The first measurement of the cross section for incoherent photonuclear production of J/$\psi$ vector meson as a function of the Mandelstam $|t|$ variable is presented. The measurement was carried out with the ALICE detector at midrapidity, $|y|<0.8$, using ultra-peripheral collisions of Pb nuclei at a centre-of-mass energy per nucleon pair $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV.

Observation of medium-induced yield enhancement and acoplanarity broadening of low-$p_\mathrm{T}$ jets from measurements in pp and central Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV / ALICE Collaboration
The ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high transverse momentum (high $p_{\rm T}$) hadron trigger in proton$-$proton and central Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV. A data-driven statistical method is used to mitigate the large uncorrelated background in central Pb$-$Pb collisions. [...]

K$^{*}$(892)$^{\pm}$ resonance production in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV / ALICE Collaboration
The production of K$^{*}$(892)$^{\pm}$ meson resonance is measured at midrapidity ($|y|<$ 0.5) in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}} =$ 5.02 TeV using the ALICE detector at the Large Hadron Collider. The resonance is reconstructed via its hadronic decay channel K$^{*}$(892)$^{\pm} \rightarrow \mathrm{K^{0}_{S} \pi^{\pm}}$. [...]

Femtoscopic correlations of identical charged pions and kaons in pp collisions at $\sqrt{s}$ = 13 TeV / ALICE Collaboration
Collective behavior has been observed in high-energy heavy-ion collisions for several decades. Collectivity is driven by the high particle multiplicities that are produced in these collisions. [...]
