Description
ALICE experiment observations at the LHC show that strange to non-strange hadron yield ratios increase with charged-particle multiplicity. This smooth evolution spans three orders of magnitude across collision systems, eventually saturating in central Pb–Pb collisions. To explain this strangeness production in small systems, models such as statistical hadronization with canonical suppression and color rope hadronization with color reconnection have been proposed.
In this contribution, we present measurements of strange-hadron production inside and outside jets as a function of event multiplicity in pp and p–Pb collisions, using complementary techniques and exploring the statistics collected by ALICE during Run 2 and Run 3. New results are reported on strange and multi-strange particle production in and out of jets, obtained with full jet reconstruction, as well as with two-particle azimuthal correlations between high-$p_{\mathrm{T}}$ charged hadrons and identified strange particles. The results are compared with state-of-the-art model predictions, providing new insights into the interplay between hard and soft QCD processes governing strangeness production in small collision systems.
