Decoding Chemical Potential Effects at the Kinetic Freeze-Out through Tsallis Non-Extensive Statistics at the LHC / Pradhan, Girija Sankar (Indian Inst. Tech., Indore) ; Sahu, Dushmanta (Indian Inst. Tech., Indore) ; Rath, Rutuparna (INFN, Bologna) ; Sahoo, Raghunath (Indian Inst. Tech., Indore) ; Cleymans, Jean (UCT-CERN Res. Ctr. ; Cape Town U.)
At the LHC energies near chemical freezeout, the chemical potential is expected to be zero due to particles and antiparticles being produced almost in equal numbers. However, considering the same case at the kinetic freezeout temperature is not trivial. [...]

Measurement of (anti)nuclei production in p-Pb collisions at sNN=8.16 TeV / ALICE Collaboration
Measurements of (anti)proton, (anti)deuteron, and (anti)3He production in the rapidity range 1<y<0 as a function of the transverse momentum and event multiplicity in p-Pb collisions at a center-of-mass energy per nucleon-nucleon pair sNN=8.16 TeV are presented. The coalescence parameters B2 and B3, measured as a function of the transverse momentum per nucleon and of the mean charged-particle multiplicity density, confirm a smooth evolution from low to high multiplicity across different collision systems and energies. [...]

System-size dependence of the charged-particle pseudorapidity density at sNN=5.02 TeV for pp, p-Pb, and Pb-Pb collisions / ALICE Collaboration
We present and compare the charged-particle pseudorapidity densities for pp, pPb, and PbPb collisions at sNN=5.02 TeV measured over a wide pseudorapidity range (3.5<η<5), using ALICE at the Large Hadron Collider. The distributions for pPb and PbPb collisions are determined as a function of the centrality of the collisions, while results from pp collisions are reported for inelastic events with at least one charged particle at midrapidity. [...]

Measurement of anti-3He nuclei absorption in matter and impact on their propagation in the Galaxy / ALICE Collaboration
Antimatter particles such as positrons and antiprotons abound in the cosmos. Much less common are light antinuclei, composed of antiprotons and antineutrons, which can be produced in our galaxy via high-energy cosmic-ray collisions with the interstellar medium or could also originate from the annihilation of the still undiscovered dark-matter particles.

Measurement of beauty production via non-prompt D0 mesons in Pb-Pb collisions at sNN= 5.02 TeV / ALICE Collaboration
The production of non-prompt D0 mesons from beauty-hadron decays was measured at midrapidity (|y|<0.5) in PbPb collisions at a nucleonnucleon center-of-mass energy of sNN=5.02 TeV with the ALICE experiment at the LHC. Their nuclear modification factor (RAA), measured for the first time down to pT=1 GeV/c in the 010% and 3050% centrality classes, indicates a significant suppression, up to a factor of about three, for pT>5 GeV/c in the 010% central PbPb collisions.

Multiplicity dependence of charged-particle jet production in pp collisions at s=13 TeV / ALICE Collaboration
The multiplicity dependence of jet production in pp collisions at the centre-of-mass energy of s=13 TeV is studied for the first time. Jets are reconstructed from charged particles using the anti-kT algorithm with resolution parameters R varying from 0.2 to 0.7. [...]

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 pD and p¯D+ pairs are measured by the ALICE Collaboration in high-multiplicity pp collisions at s=13 TeV. [...]

Forward rapidity J/ψ production as a function of charged-particle multiplicity in pp collisions at s= 5.02 and 13 TeV / ALICE Collaboration
The production of J/ψ is measured as a function of charged-particle multiplicity at forward rapidity in protonproton (pp) collisions at center-of-mass energies s= 5.02 and 13 TeV. The J/ψ mesons are reconstructed via their decay into dimuons in the rapidity interval (2.5 <y< 4.0), whereas the charged-particle multiplicity density (\dnchdeta) is measured at midrapidity (|η|<1).

Neutral to charged kaon yield fluctuations in PbPb collisions at sNN = 2.76 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst.

We present the first measurement of event-by-event fluctuations in the kaon sector in PbPb collisions at sNN= 2.76 TeV with the ALICE detector at the LHC. The robust fluctuation correlator νdyn is used to evaluate the magnitude of fluctuations of the relative yields of neutral and charged kaons, as well as the relative yields of charged kaons, as a function of collision centrality and selected kinematic ranges.

Constraining hadronization mechanisms with Λc+/D0 production ratios in Pb–Pb collisions at sNN = 5.02 TeV / ALICE Collaboration
The production of prompt Λc+ baryons at midrapidity (|y| < 0.5) was measured in central (0–10%) and mid-central (30–50%) Pb–Pb collisions at the center-of-mass energy per nucleon–nucleon pair sNN = 5.02 TeV with the ALICE detector. The Λc+ production yield, the Λc+/D0 production ratio, and the Λc+ nuclear modification factor RAA are reported. [...]
