Measurements of event-by-event fluctuations of charged-particle multiplicities in Pb–Pb collisions at √sNN = 2.76 TeV using the ALICE detector at the CERN Large Hadron Collider (LHC) are presented in the pseudorapidity range |η|<0.8 and transverse momentum 0.2<2.0 GeV/c. The amplitude of the fluctuations is expressed in terms of the variance normalized by the mean of the multiplicity distribution. The η and pT dependences of the fluctuations and their evolution with respect to collision centrality are investigated. The multiplicity fluctuations tend to decrease from peripheral to central collisions. The results are compared to those obtained from HIJING and AMPT Monte Carlo event generators as well as to experimental data at lower collision energies. Additionally, the measured multiplicity fluctuations are discussed in the context of the isothermal compressibility of the high-density strongly-interacting system formed in central Pb–Pb collisions.

Evolution of eccentricities induced by geometrical and quantum fluctuations in proton-nucleus collisions
Demirci, S.; Guerrero-Rodríguez, P. (American Physical Society (APS), 2023)We compute the azimuthal eccentricities arising from initial stage fluctuations in high energy proton-nucleus collisions at proper times τ≥0+. We consider two sources of fluctuations, namely the geometrical structure of ... -
Transverse-momentum and event-shape dependence of D-meson flow harmonics in Pb–Pb collisions at √sNN = 5.02 TeV
ALICE Collaboration (Elsevier BV, 2021)The elliptic and triangular flow coefficients v2 and v3 of prompt D0, D+, and D⁎+ mesons were measured at midrapidity (|y|<0.8) in Pb–Pb collisions at the centre-of-mass energy per nucleon pair of √sNN=5.02TeV with the ... -

ALICE collaboration (Springer, 2021)Measurements of elliptic (v2) and triangular (v3) flow coefficients of π±, K±, p+p¯, K0S, and Λ+Λ¯ obtained with the scalar product method in Xe-Xe collisions at √sNN = 5.44 TeV are presented. The results are obtained in ... -
Polarization of Λ and ¯Λ Hyperons along the Beam Direction in Pb-Pb Collisions at √sNN = 5.02 TeV
ALICE Collaboration (American Physical Society, 2022)The polarization of the Λ and ¯Λ hyperons along the beam (z) direction, Pz, has been measured in Pb-Pb collisions at √sNN = 5.02TeV recorded with ALICE at the Large Hadron Collider (LHC). The largest contribution to Pz ... -
Systematic study of nuclear effects in p+Al, p+Au, d+Au, and 3He+Au collisions at √sNN = 200 GeV using π0 production
PHENIX Collaboration (American Physical Society (APS), 2022)The PHENIX Collaboration presents a systematic study of inclusive π0 production from p+p, p+Al, p+Au, d+Au, and 3He+Au collisions at √sNN = 200 GeV. Measurements were performed with different centrality selections as well ...
