Description
Measurements of strange hadron production in pp and p-Pb collisions had been used as a reference for the study of the so-called strangeness enhancement effect, occurring in heavy ion collisions where QGP formation is observed.
Recently, the ALICE Collaboration studied strangeness production in pp interactions, unveiling unexpected features in the strange hadron to pion yield ratios. These observations have been obtained by a statistical analysis of the number of strange particles in a given set of inelastic pp events. In this sense, formation rates account for the Probability Density Function (PDF) underlying the production mechanism on an average. More insightful information on the production of strange particles and, more in general, on hadronization would come from the knowledge of the full PDF.
In this work a new event-by-event technique for extracting the full PDF for single and multi-strange hadron production will be illustrated, together with first estimates on the statistical accuracy achievable by analyzing LHC Run 2 data and the soon-to-come new data from the LHC Run 3 campaign.
