The dependence of f0(980) production on the final-state charged-particle multiplicity is reported for proton–proton (pp) collisions at the centre-of-mass energy, √s = 13 TeV. The production of f0(980) is measured with the ALICE detector via the f0(980) → π+π- decay channel in a midrapidity region of |y| < 0.5. The evolution of the integrated yields and mean transverse mome…

The measurement of + production in pp collisions at √s = 13 TeV is presented. The measurement is performed at midrapidity in both minimum-bias and high multiplicity pp collisions at √s = 13 TeV. The + is reconstructed via its weak-decay topology in the decay channel + →p+π0withπ0 →γ +γ.Inanovelapproach, the neutral pion is reconstructed by combining photons that convert in…

Meson-baryon systems with strangeness content provide a unique laboratory for investigating the strong interaction and testing theoretical models of hadron structure and dynamics. In this work, the measured correlation functions for oppositely charged Ξ-K and Ξ − 𝜋 pairs obtained in high-multiplicity pp collisions at √ 𝑠 = 13 TeV at the LHC are presented. For the first tim…

This paper presents the first measurement of the angle between different jet axes (denoted as Δ𝑅axis) in Pb-Pb collisions. The measurement is carried out in the 0–10 % most-central events at √𝑠𝑁𝑁=5.02 TeV. Jets are assembled by clustering charged particles at midrapidity using the anti-𝑘T algorithm with resolution parameters 𝑅=0.2 and 0.4 and transverse momenta in the in…

The correlations between event-by-event fluctuations of symmetry planes are measured in Pb-Pb collisions at a center-of-mass energy per nucleon pair √𝑠𝑁𝑁=5.02TeV recorded by the ALICE detector at the Large Hadron Collider. This analysis is conducted using the Gaussian estimator technique, which is insensitive to biases from correlations between different flow amplitudes.…

We report on the measurement of inclusive, non-prompt, and prompt J/ψ-hadron correlations by the ALICE Collaboration at the CERN Large Hadron Collider in pp collisions at a center-of-mass energy of 13TeV. The correlations are studied at midrapidity (|y| < 0.9) in the transverse momentum ranges pT < 40GeV/c for the J/ψ and 0.15 < pT < 10GeV/c and |η| < 0.9 for the associate…

The nuclear modification factor 𝑅AA of charm jets, identified by the presence of a D0 meson among the jet constituents, has been measured for the first time in Pb–Pb collisions at a centre-of-mass energy per nucleon pair √ 𝑠NN = 5.02 TeV with the ALICE detector at the LHC. The D0 mesons and their charge conjugates are reconstructed from the hadronic decay D0 → K−𝜋+. Jets a…

The production yields of the orbitally excited charm-strange mesons Ds1(1+)(2536)+ and D*s2(2+)(2573)+ were measured for the first time in proton-proton (pp) collisions at a center-of-mass energy of √𝑠 =13 TeV with the ALICE experiment at the LHC. The D+s1 and D*+s2 mesons were measured at midrapidity (|𝑦|

The momentum-differential invariant cross sections of π0 and η mesons are reported for pp collisions at = 13 TeV at midrapidity (|y| < 0.8). The measurement is performed in a broad transverse-momentum range of 0.2 < pT < 200 GeV/c and 0.4 < pT < 60 GeV/c for the π0 and η, respectively, extending the pT coverage of previous measurements. Transverse-mass-scaling violation of…

Correlations between event-by-event fluctuations of anisotropic flow harmonics are measured in Pb-Pb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV, as recorded by the ALICE detector at the LHC. This study presents correlations up to the hexagonal flow harmonic 𝑣6, which was measured for the first time. The magnitudes of these higher-order correlations…
