dc.description.abstract | We present measurements of two-particle correlations with neutral pion trigger particles of transverse momenta 8 < ptrigT < 16 GeV/c and associated charged particles of 0.5 < passocT < 10 GeV/c versus the azimuthal angle difference ϕ at midrapidity in pp and central Pb–Pb collisions at √sNN = 2.76 TeVwith ALICE. The new measurements exploit associated charged hadrons down to 0.5 GeV/c, which significantly extends our previous measurement that only used charged hadrons above 3 GeV/c. After subtracting the contributions of the flow background, v2 to v5, the per-trigger yields are extracted for |_ϕ| < 0.7 on the near and for |_ϕ−π| < 1.1on the away side. The ratio of per-trigger yields in Pb–Pb to those in pp collisions, IAA, is measured on the near and away side for the 0–10%most central Pb–Pb collisions. On the away side, the per-trigger yields in Pb–Pb are strongly suppressed to the level of IAA ≈ 0.6for passocT > 3GeV/c, while with decreasing momenta an enhancement develops reaching about 5 at low passocT. On the near side, an enhancement of IAAbetween 1.2at the highest to 1.8 at the lowest passocTis observed. The data are compared to parton-energy-loss predictions of the JEWEL and AMPT event generators, as well as to a perturbative QCD calculation with medium-modified fragmentation functions. All calculations qualitatively describe the away-side suppression at high passocT. Only AMPT captures the enhancement at low passocT, both on the near and away side. However, it also underpredicts IAAabove 5GeV/c, in particular on the near-side. | nb_NO |
