Measurement of beauty-quark production in pp collisions at s=13 TeV via non-prompt D mesons / ALICE Collaboration
The pT-differential production cross sections of non-prompt D0, D+, and Ds+ mesons originating from beauty-hadron decays are measured in proton--proton collisions at a centre-of-mass energy s of 13 TeV. The measurements are performed at midrapidity, |y|<0.5, with the data sample collected by ALICE from 2016 to 2018. [...]

Studying the interaction between charm and light-flavor mesons / ALICE Collaboration
The two-particle momentum correlation functions between charm mesons (D± and D±) and charged light-flavor mesons (π± and K±) in all charge-combinations are measured for the first time by the ALICE Collaboration in high-multiplicity proton-proton collisions at a center-of-mass energy of s=13 TeV. For DK and DK pairs, the experimental results are in agreement with theoretical predictions of the residual strong interaction based on quantum chromodynamics calculations on the lattice and chiral effective field theory. [...]

Investigating the nature of the K0(700) state with π±KS0 correlations at the LHC / ALICE Collaboration
The first measurements of femtoscopic correlations with the particle pair combinations π±KS0 in pp collisions at s=13 TeV at the Large Hadron Collider (LHC) are reported by the ALICE experiment. Using the femtoscopic approach, it is shown that it is possible to study the elusive K0(700) particle that has been considered a tetraquark candidate for over forty years. [...]

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.

Common femtoscopic hadron-emission source in pp collisions at the LHC / ALICE Collaboration
The femtoscopic study of pairs of identical pions is particularly suited to investigate the effective source function of particle emission, due to the resulting Bose-Einstein correlation signal. In small collision systems at the LHC, pp in particular, the majority of the pions are produced in resonance decays, which significantly affect the profile and size of the source. [...]

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.

Multiplicity dependence of charged-particle intra-jet properties in pp collisions at s = 13 TeVMultiplicity dependence of charged-particle intra-jet properties in pp collisions at \varvecs = 13 TeV / ALICE Collaboration
The first measurement of the multiplicity dependence of intra-jet properties of leading charged-particle jets in protonproton (pp) collisions is reported. The mean charged-particle multiplicity and jet fragmentation distributions are measured in minimum-bias and high-multiplicity pp collisions at center-of-mass energy s = 13 TeV using the ALICE detector.

Observation of abnormal suppression of f0(980) production in pPb collisions at sNN = 5.02 TeV / ALICE Collaboration
The dependence of f0(980) production on the final-state charged-particle multiplicity in pPb collisions at sNN=5.02 TeV is reported. The production of f0(980) is measured with the ALICE detector via the f0(980)π+π decay channel in a midrapidity region of 0.5<y<0. [...]

Measurement of (anti)alpha production in central PbPb collisions at sNN = 5.02 TeV / ALICE Collaboration
In this letter, measurements of (anti)alpha production in central (0-10%) Pb--Pb collisions at a center-of-mass energy per nucleon--nucleon pair of sNN = 5.02 TeV are presented, including the first measurement of an antialpha transverse-momentum spectrum. Owing to its large mass, (anti)alpha production yields and transverse-momentum spectra are of particular interest because they provide a stringent test of particle production models. [...]

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. [...]
