Résumé :

Baryon number violation (BNV) in R-parity violating (RPV) supersymmetry is studied with a focus on ΔB = 2 processes which allow neutron-anti-neutron (n-n) oscillations. Simplified RPV-SUSY models, including only the relevant superpartners and couplings, are considered. Constraints from flavour physics, searches at the Large Hadron Collider and searches at dedicated BNV experiments are quantified for the various scenarios at the TeV scale. It is also shown that a proposed n-n experiment at the European Spallation Source has a sensitivity to a mass scale for new physics that goes beyond all other experiments and up to the PeV scale for certain regions of parameter space.
