Abstract

We present measurements of two-particle correlations with neutral pion trigger particles of transverse momenta View the MathML source83 GeV/c, while with decreasing momenta an enhancement develops reaching about 5 at low View the MathML sourcepTassoc. On the near side, an enhancement of IAAIAA between 1.2 at the highest to 1.8 at the lowest View the MathML sourcepTassoc is 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 View the MathML sourcepTassoc. Only AMPT captures the enhancement at low View the MathML sourcepTassoc, both on the near and away side. However, it also underpredicts IAAIAA above 5 GeV/c5 GeV/c, in particular on the near-side.
