Abstract The project to be developed during the one year research stay in the Institut de Physique Nucleaire d'Orsay (INPO), under supervision of Prof. Jaume Carbonell, has two general goals: (i) perform theoretical studies of antiprotonic atoms, and (ii) solve the two- and three-body Bethe-Salpeter equations in Minkowski space. For the first goal, we will compute the annihilation rates and widths of protonium for different antinucleon-nucleon interactions by solving the coupled-channel Schroedinger equation. Furthermore, we plan to study light antiprotonic atoms by solving the Faddeev-Yakubovski equations.This study has important implications for experiments, e.g.~ the proposed PUMA (anti-Proton Unstable Matter Annihilation) experiment at CERN, aiming at using antiprotons for studies of neutron skin and halo nuclei. For the second goal, we will extend our studies of the two- and three-body Bethe-Salpeter equations in Minkowski space exploring both numerically and formally the associated singular integral equations. A special effort will be devoted to study both the bound and scattering states of the two-fermion or fermion-antifermion systems. In the scattering regime this framework could be used to study the relativistic effects on nucleon-antinucleon interactions. Additionally, we plan to explore the relativistic bound-state system of three spinless bosons with finite-range interaction, which is connected with important phenomena in nuclear and atomic physics.The project aims thus to cover applications in low energy anti-proton physics, but also in high energy relativistic physics, e.g for the description of hadrons and light nuclei. The fully relativistic treatment of few-nucleon systems will allow us, among other things, to improve the description of the neutrino-deuteron scattering cross sections in the high-energy regime. | |
