ALICE measurements of flow coefficients and their correlations in small (pp and p–Pb) and large (Xe–Xe and Pb–Pb) collision systems
(Peer reviewed; Journal article, 2019)Many observables which are used as a signature of the collective effects in heavy-ion collisions when measured in high multiplicity pp and pA interactions reveal a very similar behaviour. We will present first measurements ... -
ALICE results on system-size dependence of charged-particle multiplicity density in p–Pb, Pb–Pb and Xe–Xe collisions
(Peer reviewed; Journal article, 2019)Particle production at LHC energies involves the interplay of hard (perturbative) and soft (non-perturbative) QCD processes. Global observables, such as the charged-particle multiplicity, are related to the initial geometry ... -
Balance functions of (un)identified hadrons in Pb–Pb, p–Pb, and pp collisions at the LHC
(Peer reviewed; Journal article, 2019)In ultrarelativistic heavy-ion collisions, correlations of particles with opposite quantum numbers provide insight into quark production mechanisms and time scales, collective motion, and re-scattering in the hadronic ... -
Dielectron measurements in pp and Pb–Pb colllisions with ALICE at the LHC
(Peer reviewed; Journal article, 2019)The production of low-mass dielectrons is one of the most promising tools for the investigation of chiral symmetry restoration and thermal radiation from the QGP created in heavy-ion collisions. To single out the signal ... -
Direct photon elliptic flow in Pb–Pb collisions at √sNN=2.76 TeV
(Peer reviewed; Journal article, 2019)The elliptic flow of inclusive and direct photons was measured by ALICE for central and semi-central Pb–Pb collisions at √sNN = 2.76 TeV. The photons were reconstructed using the electromagnetic calorimeter PHOS and the ... -
Electroweak boson measurements in p-Pb and Pb-Pb collisions at √sNN=5.02TeV with ALICE at the LHC
(Peer reviewed; Journal article, 2019)The ALICE collaboration has measured the electroweak boson production at forward rapidity in Pb-Pb and p-Pb collisions at √sNN = 5.02 TeV. Final results on the Z0 boson production in Pb-Pb collisions are presented as a ... -
Elliptic flow of identified hadrons in small collisional systems measured with ALICE
(Peer reviewed; Journal article, 2019)Recent observations of long-range multi-particle azimuthal correlations in p–Pb and high multiplicity pp collisions provided new insights into collision dynamics and opened a possibility to study collective effects in these ... -
The evolution of the near-side peak in two-particle number and transverse momentum correlations in Pb–Pb collisions from ALICE
(Peer reviewed; Journal article, 2019)Two-particle number and transverse momentum correlations are powerful tools for studying the medium produced in heavy-ion collisions. Correlations in the angular separation of pairs of hadrons can provide information on ... -
Hadronic resonances, strange and multi-strange particle production in Xe-Xe and Pb-Pb collisions with ALICE at the LHC
(Peer reviewed; Journal article, 2019)We present measurements of hadronic resonance, strange and multi-strange particle production in collisions of Xe-Xe and Pb-Pb at the center-of-mass energies of √sNN = 5.44 and 5.02 TeV, respectively, by the ALICE collaboration ... -
Heavy-flavour hadron decay leptons in Pb–Pb and Xe–Xe collisions at the LHC with ALICE
(Peer reviewed; Journal article, 2019)Heavy quarks, i.e. charm and beauty, are sensitive probes of the medium produced in high-energy heavy-ion collisions. They are produced in the early stage of the collision, mainly in hard partonic scattering processes, and ... -
Higher moment fluctuations of identified particle distributions from ALICE
(Peer reviewed; Journal article, 2019)Cumulants of conserved charges fluctuations are regarded as a potential tool to study the criticality in the QCD phase diagram and to determine the freeze-out parameters in a model-independent way. At LHC energies, the ... -
Measurements of anisotropic flow and flow fluctuations in Xe–Xe and Pb–Pb collisions with ALICE
(Peer reviewed; Journal article, 2019)Anisotropic flow is a key observable to characterise the system created in heavy-ion collisions, as it is sensitive to the system’s initial state, transport properties, the equation of state and freeze-out conditions. In ... -
Measurements of the chiral magnetic effect in Pb–Pb collisions with ALICE
(Peer reviewed; Journal article, 2019)We present the measurement of the charge-dependent 3-particle azimuthal correlation for unidentified charged particles in Pb–Pb collisions at √sNN = 5.02 TeV in ALICE. The results are compared with corresponding results ... -
Open heavy-flavour production and elliptic flow in p-Pb collisions at the LHC with ALICE
(Peer reviewed; Journal article, 2019)Measurements of open heavy flavour production in p–A collisions allow the investigation of Cold Nuclear Matter effects. In addition, they are an important tool for a complementary investigation of the long-range correlations ... -
Quarkonium measurements in nucleus–nucleus collisions with ALICE
(Peer reviewed; Journal article, 2019)Quarkonia, i.e. bound states of bb¯ and cc¯ quarks, are powerful observables to study the properties of nuclear matter under extreme conditions. The formation of a Quark-Gluon Plasma (QGP), which is predicted by lattice ... -
