$$\mathrm {K_S}^{0}$$ K S 0 - and (anti-) $$\Lambda $$ Λ -hadron correlations in pp collisions at $${\sqrt{s}} = 13$$ s = 13 TeV

Two-particle Azimuthal correlations are measured with the ALICE apparatus in pp collisions at $$\sqrt{s} = 13$$ TeV to explore strangeness- and multiplicity-related effects in the fragmentation of jets and the transition regime between bulk and hard production, probed with the condition that a strange meson ( $$\mathrm {K_S}^{0}$$ ) or baryon ( $$\Lambda $$ ) with transverse momentum $$p_{\mathrm T} >3$$ GeV/ $$c$$ is produced. Azimuthal correlations between kaons or $$\Lambda $$ hyperons with other hadrons are presented at midrapidity for a broad range of the trigger ( $$3< p_\mathrm {T}^\mathrm {trigg} < 20$$ GeV/ $$c$$ ) and associated particle $$p_{\mathrm T}$$ (1 GeV/ $$c$$ $$< p_\mathrm {T}^\mathrm {assoc} < p_\mathrm {T}^\mathrm {trigg} $$ ), for minimum-bias events and as a function of the event multiplicity. The near- and away-side peak yields are compared for the case of either $$\mathrm {K_S}^{0}$$ or $$\Lambda $$ ( $${\overline{\Lambda }}$$ ) being the trigger particle with that of inclusive hadrons (a sample dominated by pions). In addition, the measurements are compared with predictions from PYTHIA 8 and EPOS LHC event generators.
