Description
Two-particle correlations with $V^{0}$ $(K^{0}_{S}, \Lambda/\bar\Lambda)$ and charged hadrons as trigger particles of transverse momentum
$8 < p_\mathrm{T,trig}< 16$ GeV/c, and associated charged particles of $1 < p_\mathrm{T,assoc}< 8$ GeV/c, are studied at mid-rapidity in pp and most central Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV with the ALICE detector at the LHC.
After contributions of the flow background is subtracted, the per-trigger yields are extracted, and the nuclear modification factor, $I_\mathrm{AA}$, is calculated on both near and away side.
The results of $I_\mathrm{AA}$ show strongly suppression on away-side and enhancement at low $p_\mathrm{T}$ on both near- and away-side consistence with previous ALICE measurement of neutral pion ($\pi^{0}$-h) and charged hadrons (h-h) in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 2.76 TeV. In addition, the data are described within uncertainties by AMPT and HIJING event generators.
