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 strang...

Description
Summary: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.
