Correlations between jets and charged particles in PbPb and pp collisions at s N N = 2.76 $$\sqrt{s_{\mathrm{NN}}}=2.76$$ TeV. Journal of High Energy Physics, 2016(2). doi:10.1007/jhep02(2016)156 en_US dc.identifier.uri http://hdl.handle.net/1808/24995 dc.description.abstract The quark-gluon plasma is studied via medium-induced changes to correlations between jets and charged particles in PbPb collisions compared to pp reference data. This analysis uses data sets from PbPb and pp collisions with integrated luminosities of 166 μb−1 and 5.3 pb−1, respectively, collected at sNN−−−√=2.76 TeV. The angular distributions of charged particles are studied as a function of relative pseudorapidity (Δη) and relative azimuthal angle (Δϕ) with respect to reconstructed jet directions. Charged particles are correlated with all jets with transverse momentum (pT) above 120 GeV, and with the leading and subleading jets (the highest and second-highest in pT, respectively) in a selection of back-to-back dijet events. Modifications in PbPb data relative to pp reference data are characterized as a function of PbPb collision centrality and charged particle pT. A centrality-dependent excess of low-pT particles is present for all jets studied, and is most pronounced in the most central events. This excess of low-pT particles follows a Gaussian-like distribution around the jet axis, and extends to large relative angles of Δη ≈ 1 and Δϕ ≈ 1. en_US dc.publisher Elsevier en_US dc.rights This is an open access article under the terms of the Creative Commons Attribution License 4.0 (CC BY4.0). en_US dc.rights.uri http://creativecommons.org/licenses/by/4.0/ en_US dc.subject Jets en_US dc.subject Heavy-ion collision en_US dc.subject Heavy Ion Experiments en_US dc.subject Particle correclations and fluctuations en_US dc.title Correlations between jets and charged particles in PbPb and pp collisions at sNN−−−√=2.76 TeV en_US dc.type Article en_US dc.identifier.doi 10.1007/JHEP02(2016)156 en_US kusw.oaversion Scholarly/refereed, publisher version en_US kusw.oapolicy This item meets KU Open Access policy criteria. en_US dc.rights.accessrights openAccess
