The Pauli exclusion principle (PEP) has been tested for nucleons (n,p) in 12C nuclei with the Borexino detector. The approach consists of a search for γ, n, p and β± emitted in a non-Paulian transition of 1P3/2-shell nucleons to the filled 1S1/2 shell in nuclei. Due to the extremely low background and the large mass of the Borexino detector, the most stringent/competitive up-to-date experimental bounds on PEP-violating transitions of nucleons and on the relative strengths for non-Paulian electromagnetic, strong and weak transitions have been established. --------------------------- Kirill Fomenko JINR Dubna
