Abstract: (arXiv)
The Pauli exclusion principle (PEP) has been tested for nucleons () in and nuclei, using the results of background measurements with the prototype of the Borexino detector, the Counting Test Facility (CTF). The approach consisted of a search for , , and/or 's emitted in a non-Paulian transition of 1- shell nucleons to the filled 1 shell in nuclei. Similarly, the Pauli-forbidden decay processes were searched for. Due to the extremely low background and the large mass (4.2 tons) of the CTF detector, the following most stringent up-to-date experimental bounds on PEP violating transitions of nucleons have been established: y, y, y, y, y and y, all at 90% C.L.Note:
