Three-body strong interaction studied using femtoscopic correlation functions
One of the main challenges of the modern era in particle physics is to obtain a quantitative description of the three-body strong interaction among particles, such as nucleons and hyperons. Three-body forces are indeed crucial for the understanding of the nuclear structure as well as the inner composition of compact stellar objects like the neutron stars. Nevertheless, an accurate microscopic description of the three-body problem is still far from being achieved and precise experimental data to test the existing models are strongly demanded. In recent years, the ALICE Collaboration at the Large Hadron Collider (LHC) provided unprecedented experimental information on the two-body strong interaction among particle pairs using the femtoscopy technique (for a complete review see [1]). The interaction models are constrained by studying the particle correlation in the momentum space. The extension of such a powerful technique to the case of three-particle systems is currently under development, in view of the future LHC Run-3 data-taking which will allow to probe the three-body interactions. The student will contribute to the development of the three-body femtoscopy by studying the shape of the correlation functions in the case of attractive and repulsive three-body potentials. To this end, the student will perform analytical calculations at the second order of the perturbation theory in Quantum Mechanics using the available potential models and will make use of toy Monte Carlo simulations to produce the expected correlation functions.
