Description
The Lednický-Lyuboshitz formalism was claimed to inadequately describe the proton-deuteron femtoscopy correlation function measured by the ALICE collaboration in high-multiplicity p+p collisions. This result motivated a full three-particle description involving a composite deuteron, leading to a much better agreement with the experimental data. Building on the two-body approach, we solve the complete wave function of the system by solving the Schrödinger equation with both strong and Coulomb potentials, including also higher partial waves beyond the S-wave. Our results show significant differences compared to the Lednický-Lyuboshitz model, providing a better match to the ALICE measurements and also aligning with recent STAR data in Au+Au collisions for the proton-deuteron system.
