Description

Measurements of the relative production of strange hadrons in high-energy hadronic collisions have proven to be an important tool for understanding hadronization. In particular, it has been shown that strangeness is produced more abundantly in high-multiplicity pp and p-Pb collisions at the LHC, a phenomenon known as "strangeness enhancement" that has sparked significant interest in both the experimental and theoretical communities.

In this work, correlations between strange hadrons and high-$p_\{\rm\{T\}\}$ charged particles are investigated. The results are shown for both Run 2 and Run 3 data-taking periods, the latter providing a significantly larger amount of data and thus allowing a better determination of strangeness-production mechanisms. As these measurements serve as crucial input for phenomenological models aiming to describe the strangeness enhancement, we also discuss how the models are compared with the data.
