Description

Femtoscopy is a powerful tool that uses correlation techniques to probe the interactions between hadrons. In Run 2 of the LHC, the ALICE Collaboration confirmed, based on the measurement of kaon-deuteron correlations, that particle pairs involving one deuteron exhibit the same transverse mass scaling as other hadron-hadron pairs, consistent with predictions from the resonance source model. Building on this, femtoscopic studies were extended to the proton-deuteron (p–d) system, where significant three-body dynamics emerged, exposing limitations in models considering only two-body interactions. However, these measurements were ultimately limited by the statistics in the available data sample. With the transition to Run 3 and access to a dataset two orders of magnitude larger, the primary objective is now to conduct a comprehensive study of the p–d system. This contribution presents the initial measurements of the correlation between protons and deuterons using data collected by the ALICE experiment in pp collisions at √s = 13.6 TeV during Run 3 of the LHC.
