The pTpT-differential cross section of ωω meson production in pp collisions at ss = 13 TeV at midrapidity (|y|<0.5|y|<0.5) was measured with the ALICE detector at the LHC, covering an unprecedented transverse-momentum range of 1.6<pT<501.6<pT<50 GeV/cc. The meson is reconstructed via the ωπ+ππ0ωπ+ππ0 decay channel. [...]

The intense photon fluxes from relativistic nuclei provide an opportunity to study photonuclear interactions in ultraperipheral collisions. The measurement of coherently photoproduced π+ππ+ππ+ππ+π final states in ultraperipheral Pb-Pb collisions at sNN=5.02sNN=5.02 TeV is presented for the first time. [...]

Systematic study of flow vector fluctuations in sNN=5.02sNN=5.02 TeV Pb-Pb collisions / ALICE Collaboration
Measurements of the pTpT-dependent flow vector fluctuations in Pb--Pb collisions at sNN=5.02 TeVsNN=5.02 TeV using azimuthal correlations with the ALICE experiment at the LHC are presented. A four-particle correlation approach [1] is used to quantify the effects of flow angle and magnitude fluctuations separately. [...]

Measurement of beauty-quark production in pp collisions at s=13s=13 TeV via non-prompt D mesons / ALICE Collaboration
The pTpT-differential production cross sections of non-prompt D00, D++, and D+s+s mesons originating from beauty-hadron decays are measured in proton--proton collisions at a centre-of-mass energy ss of 13 TeV. The measurements are performed at midrapidity, |y|<0.5|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±D± and D±D±) and charged light-flavor mesons (π±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=13s=13 TeV. For DKDK and DKDK 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 K00(700) state with π±π±K0S0S correlations at the LHC / ALICE Collaboration
The first measurements of femtoscopic correlations with the particle pair combinations π±π±K0S0S in pp collisions at s=13s=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)0(700) particle that has been considered a tetraquark candidate for over forty years. [...]

Design and characterisation of a new FoCal-E prototype for ALICE experiment / Ghimouz, Abderrahmane (Tsukuba U. (main)) /FoCal Collaboration
The FoCal-E detector is a part of the FoCal detector aiming to provide unique capabilities to measure small-x gluon distributions via prompt photon production. It represents an upgrade to the ALICE experiment, and will be installed during LS3 for data taking in 2029–2032 at the LHC. [...]

Measurements of Chemical Potentials in Pb–Pb collisions at sNN=5.02sNN=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=5.02sNN=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±0.90μQ=0.18±0.90 MeV and μB=0.71±0.45μB=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 ss = 13 TeV. Long-range ridge yields are extracted for pairs of charged particles with a pseudorapidity difference of 1.4<|Δη|<1.81.4<|Δη|<1.8 and a transverse momentum of 1<pT<21<pT<2 GeV/cc, as a function of the charged-particle multiplicity measured at mid-rapidity.
