      Two-particle correlations with K0S, /, and charged hadrons as trigger particles in the transverse momentum range 8<16 GeV/c, and associated charged particles within 1<8 GeV/c, are studied at midrapidity in pp and central Pb–Pb collisions at a centre-of-mass energy per nucleon–nucleon collision √sNN = 5.02 TeV with the ALICE detector at the LHC. After subtracting the contributions of the flow background, the per-trigger yields are extracted on both the near and away sides, and the ratio in Pb–Pb collisions with respect to pp collisions (IAA) is computed. The per-trigger yield in Pb–Pb collisions on the away side is strongly suppressed to the level of IAA ≈ 0.6 for pT,assoc > 3 GeV/c as expected from strong in-medium energy loss, while an enhancement develops at low pT,assoc on both the near and away sides, reaching IAA ≈ 1.8 and 2.7 respectively. These findings are in good agreement with previous ALICE measurements from two-particle correlations triggered by neutral pions (π0–h) and charged hadrons (h–h) in Pb–Pb collisions at √sNN = 2.76 TeV. Moreover, the correlations with K0S mesons and / baryons as trigger particles are compared to those of inclusive charged hadrons. The results are compared with the predictions of Monte Carlo models.
