First measurement of proton-deuteron and lambda-deuteron correlation function with data taken by ALICE in Run 3 — •Anton Riedel for the ALICE Germany collaboration — Technische Universität München, Garching, Deutschland

Femtoscopy is a powerful tool that uses correlation techniques to explore the details of how hadrons interact. In Run 2 of the LHC, the ALICE collaboration extended its femtoscopic studies to nuclei, investigating the correlation between protons and deuterons (p–d). The measurement hinted at the presence of significant three-body dynamics in the p–d system but was ultimately limited by the available statistics. As we transition into Run 3 of the LHC, where we have access to more data by two orders of magnitude, our goal is to conduct a more in-depth study of the p–d system. Additionally, we aim to take a preliminary look at the lambda-deuteron system (Λ–d). This poster presents the initial measurements of the correlation between protons and deuterons, as well as between lambdas and deuterons, using data collected by the ALICE experiment in pp collisions at √s=13.6 TeV during Run 3 of the LHC. This project has been funded by the DFG under Germany’s Excellence Strategy - EXC2094 - 390783311 and by BMBF Verbundforschung (05P21WOCA1 ALICE).
