Description

We present the VIP2 experimental method to look for possible small violations of the Pauli Exclusion Principle (PEP) for electrons, through the search for "anomalous" X-ray transitions in copper atoms, produced by "fresh" electrons (brought inside the copper bar by circulating current) which can have the probability to do the Pauli-forbidden transition to the 1 s level already occupied by two electrons. We describe the VIP2 (VIolation of PEP) upgraded setup which is taking data at the Gran Sasso underground laboratories, searching for these Pauli-prohibited transitions. We will report new results of data analyses, showing a limit better than the previous VIP2 one, together with future plans.
