Abstract

The azimuthal anisotropy of particles associated with jets (jet particles) at midrapidity is measured for the first time in p-Pb and Pb-Pb collisions at √sNN = 5.02 TeV down to transverse momentum (pT) of 0.5 GeV/c and 2 GeV/c, respectively, with ALICE. The second-order Fourier coefficient of the jet-particle azimuthal distribution (v2) in high-multiplicity p-Pb collisions is positive, with a significance reaching 6.8σ at low pT. Comparisons with the inclusive charged-particle v2 and with AMPT calculations are discussed. The model describes qualitatively the main features of the jet-particle v2 in high-multiplicity p-Pb collisions and indicates that the positive jet-particle v2 is generated by parton interactions.
