Journal of High Energy Physics, 2020(9), Article 160. https://doi.org/10.1007/JHEP09(2020)160 dc.identifier.other CONVID_42217762 dc.identifier.uri https://jyx.jyu.fi/handle/123456789/72025 dc.description.abstract Systematic studies of charge-dependent two- and three-particle correlations in Pb-Pb collisions at √sNN = 2.76 and 5.02 TeV used to probe the Chiral Magnetic Effect (CME) are presented. These measurements are performed for charged particles in the pseudorapidity (η) and transverse momentum (pT) ranges |η| < 0.8 and 0.2 < pT < 5 GeV/c. A significant charge-dependent signal that becomes more pronounced for peripheral collisions is reported for the CME-sensitive correlators γ1, 1 = 〈cos(φα + φβ − 2Ψ2)〉 and γ1, − 3 = 〈cos(φα − 3φβ + 2Ψ2)〉. The results are used to estimate the contribution of background effects, associated with local charge conservation coupled to anisotropic flow modulations, to measurements of the CME. A blast-wave parametrisation that incorporates local charge conservation tuned to reproduce the centrality dependent background effects is not able to fully describe the measured γ1,1. Finally, the charge and centrality dependence of mixed-harmonics three-particle correlations, of the form γ1, 2 = 〈cos(φα + 2φβ − 3Ψ3)〉, which are insensitive to the CME signal, verify again that background contributions dominate the measurement of γ1,1. en dc.format.mimetype application/pdf dc.language eng dc.language.iso eng dc.publisher Springer dc.relation.ispartofseries Journal of High Energy Physics dc.rights CC BY 4.0 dc.subject.other Hadron-Hadron scattering (experiments) dc.title Constraining the Chiral Magnetic Effect with charge-dependent azimuthal correlations in Pb-Pb collisions at √sNN = 2.76 and 5.02 TeV dc.type article dc.identifier.urn URN:NBN:fi:jyu-202010066081 dc.contributor.laitos Fysiikan laitos fi dc.contributor.laitos Department of Physics en dc.contributor.oppiaine Ydin- ja kiihdytinfysiikan huippuyksikkö fi dc.contributor.oppiaine Fysiikka fi dc.contributor.oppiaine Centre of Excellence in Nuclear and Accelerator Based Physics en dc.contributor.oppiaine Physics en dc.type.uri http://purl.org/eprint/type/JournalArticle dc.description.reviewstatus peerReviewed dc.relation.issn 1126-6708 dc.relation.numberinseries 9 dc.relation.volume 2020 dc.type.version publishedVersion dc.rights.copyright © CERN, for the benefit of the ALICE Collaboration.
