Observation of flow angle and flow magnitude fluctuations in Pb-Pb collisions at sNN = 5.02 TeV at the LHC / ALICE Collaboration
This Letter reports on the first measurements of transverse momentum dependent flow angle Ψn and flow magnitude vn fluctuations, determined using new four-particle correlators. The measurements are performed for various centralities in Pb-Pb collisions at a centre-of-mass energy per nucleon pair of sNN = 5.02 TeV with ALICE at the CERN Large Hadron Collider. [...]

Measurements of Chemical Potentials in Pb–Pb collisions at sNN=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 sNN=5.02 TeV. Using the Statistical Hadronization framework, it is possible to obtain the value of the electric charge and baryon chemical potentials, μQ=0.18±0.90 MeV and μB=0.71±0.45 MeV, with unprecedented precision. [...]

Study of flavor dependence of the baryon-to-meson ratio in proton-proton collisions at s = 13 TeV / ALICE Collaboration
The production cross sections of D0 and Λc+ 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 s=13 TeV. [...]

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 s = 13 TeV. Long-range ridge yields are extracted for pairs of charged particles with a pseudorapidity difference of 1.4<|Δη|<1.8 and a transverse momentum of 1<pT<2 GeV/c, as a function of the charged-particle multiplicity measured at mid-rapidity.

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

Observation of medium-induced yield enhancement and acoplanarity broadening of low-pT jets from measurements in pp and central PbPb collisions at sNN=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 pT) hadron trigger in protonproton and central PbPb collisions at sNN=5.02 TeV. A data-driven statistical method is used to mitigate the large uncorrelated background in central PbPb collisions. [...]

The first measurement of the cross section for incoherent photonuclear production of J/ψ vector meson as a function of the Mandelstam |t| variable is presented.

K(892)± resonance production in PbPb collisions at sNN = 5.02 TeV / ALICE Collaboration
The production of K(892)± meson resonance is measured at midrapidity (|y|< 0.5) in PbPb collisions at sNN= 5.02 TeV using the ALICE detector at the Large Hadron Collider. The resonance is reconstructed via its hadronic decay channel K(892)±KS0π±. [...]

Pseudorapidity densities of charged particles with transverse momentum thresholds in pp collisions at <math display="inline"><mrow><msqrt><mrow><mi>s</mi></mrow></msqrt><mo>=</mo><mn>5.02</mn></mrow></math> and 13 TeV / ALICE Collaboration
The pseudorapidity density of charged particles with minimum transverse momentum (pT) thresholds of 0.15, 0.5, 1, and 2 GeV/c was measured in pp collisions at centre-of-mass energies of s= 5.02 and 13 TeV with the ALICE detector. The study is carried out for inelastic collisions with at least one primary charged particle having a pseudorapidity (η) within ±0.8 and pT larger than the corresponding threshold. [...]

Femtoscopic correlations of identical charged pions and kaons in pp collisions at 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. [...]
