摘要

Two-particle correlations with K-S(0), Lambda/(Lambda) over bar, and charged hadrons as trigger particles in the transverse momentum range 8 3 GeV/c as expected from strong in-medium energy loss, while an enhancement develops at low p(T), assoc on both the near and away sides, reaching I-AA approximate to 1.8 and 2.7 respectively. These findings are in good agreement with previous ALICE measurements from two-particle correlations triggered by neutral pions (pi(0)-h) and charged hadrons (h-h) in Pb-Pb collisions at root s(NN) = 2.76 TeV. Moreover, the correlations with K-S(0) mesons and Lambda/(Lambda) over bar baryons as trigger particles are compared to those of inclusive charged hadrons. The results are compared with the predictions of Monte Carlo models.
