Abstract

The production of strange K_S⁰, Λ and multi-strange (Ξ^± and Ω^±) particles in jets and the underlying event in pp collisions at √S = 13 TeV has been studied with ALICE at the LHC. The p_T-differential density of the particles produced in a jet is compared to the inclusive distribution. The corresponding (Λ + Λ^¯)/2K_S⁰ and (Ξ⁻ + Ξ^¯+)/(Λ + Λ^¯) ratios in jets as a function of p_T are also reported in this work. The p_T-differential density distribution of hadrons associated with jets decreases slower than the one reported for inclusive particle production. The ratios measured in jets show a clear difference when compared to the inclusive ones at the intermediate p_T range. The results provide an opportunity to test the strange and multi-strange particle production mechanisms with hard scattering.
