Abstract
The VIP (Violation of Pauli exclusion principle) experiment and its follow-up experiment VIP-2 at the Laboratori Nazionali del Gran Sasso (LNGS) search for X-rays from Cu atomic states that are prohibited by the Pauli Exclusion Principle (PEP). The candidate events, if they exist, will originate from the transition of a 2p orbit electron to the ground state which is already occupied by two electrons. The present limit on the probability for PEP violation for electron is 4.7 ×10–29 set by the VIP experiment. With upgraded detectors for high precision X-ray spectroscopy, the VIP-2 experiment will improve the sensitivity by 2 orders of magnitude.

In quantum mechanics the Pauli exclusion principle can be formalized with two fundamental principles
Ramberg and Snow [5] took this argument into account, by running a high electric current through a Cu conductor, and they searched for X-rays from transitions that are PEP-forbidden after one electron is captured by a Cu atom
