Abstract
The Pauli exclusion principle (PEP) has been tested for nucleons () in with the Borexino detector. The approach consists of a search for , , , and emitted in a non-Paulian transition of -shell nucleons to the filled shell in nuclei. Due to the extremely low background and the large mass ( tons) of the Borexino detector, the following most stringent up-to-date experimental bounds on PEP violating transitions of nucleons have been established: yr, yr, yr, yr, and yr, all at C.L. The corresponding upper limits on the relative strengths for the searched non-Paulian electromagnetic, strong and weak transitions have been estimated as , , and .
