Open and hidden strangeness production study via high pT dihadron correlations in pp and p-Pb collisions with ALICE at the LHC

Two-particle correlations in and are used to study jets, in particular, their particle com- position. While in Pb-Pb collisions this is done to characterize the quark-gluon Plasma, pp and p-Pb collisions serve as a reference and are of interest on their own for their input into the under- standing of particle production mechanisms. Recent ALICE results on the production of strange particles in small systems (pp and p-Pb collisions) reveal the possibility of having similar strange hadron production mechanisms in all collision systems. We study the production mechanism of hidden strangeness ($\phi$ meson) and open strangeness ( $K_S^0$ meson) in jets via two-particle correlations between the strange hadrons and charged primary hadrons in pp collisions at $\sqrt{s}$ = 13 TeV and p-Pb at $\sqrt{s_{NN}}$ = 5.02 TeV collected with the ALICE experiment at the LHC. In this paper, the dependence of the per-trigger yields of strange hadrons on the transverse mo- menta of the trigger and associated particles, as well as on the event multiplicity, is presented on both the near-side and away-side of the h-$K_S^0$, $K_S^0$-h and h-$\phi$ correlation functions. Moreover, the ratios of these yields to the yields extracted from the h-h correlation function are shown. In addition, a comparison to different MC generators is presented.
