Abstract

One of the fundamental rules of nature and a pillar in the foundation of quantum theory and thus of modern physics is represented by the Pauli Exclusion Principle. We know that this principle is extremely well fulfilled due to many observations like the order of the elements and the stability of matter. Numerous experiments were performed to search for tiny violation of this rule in various systems. The VIP experiment at Gran Sasso underground laboratory is testing the validity of this principle for electrons with very high precision (order of 10−30). The layout of the present experiment, results obtained so far and new ideas to further increase the precision will be presented.

One of the fundamental rules of nature and a pillar in the foundation of quantum theory and thus of modern physics is represented by the Pauli Exclusion Principle. We know that this principle is extremely well fulfilled due to many observations. Numerous experiments were performed to search for tiny violation of this rule in various systems. The experiment VIP at the Gran Sasso underground laboratory is searching for possible small violations of the Pauli Exclusion Principle for electrons leading to forbidden X-ray transitions in copper atoms. VIP is aiming at a test of the Pauli Exclusion Principle for electrons with high accuracy, down to the level of 10$^{-29}$ - 10$^{-30}$, thus improving the previous limit by 3-4 orders of magnitude. The experimental method, results obtained so far and new developments within VIP2 (follow-up experiment at Gran Sasso, in preparation) to further increase the precision by 2 orders of magnitude will be presented.

High sensitivity tests of the Pauli Exclusion Principle with VIP2

Johann Marton, Sergio Bartalucci, S. Bertolucci +24 more

The Pauli Exclusion Principle is one of the most fundamental rules of nature and represents a pillar of modern physics. According to many observations the Pauli Exclusion Principle must be extremely well fulfilled. Nevertheless, numerous experimental investigations were performed to search for a small violation of this principle. The VIP experiment at the Gran Sasso underground laboratory searched for Pauli-forbidden X-ray transitions in copper atoms using the Ramberg-Snow method and obtained the best limit so far. The follow-up experiment VIP2 is designed to reach even higher sensitivity. It aims to improve the limit by VIP by orders of magnitude. The experimental method, comparison of different PEP tests based on different assumptions and the developments for VIP2 are presented.

Testing the Pauli Exclusion Principle for electrons

Johann Marton, Sergio Bartalucci, S. Bertolucci +22 more

The Pauli Principle represents one of the most important rules in physics and explains numerous phenomena as well as characteristic properties of matter, like its stability. Testing the validity of this principle at the highest possible sensitivity is a challenging experimental task - the VIP experiment at the Gran Sasso underground laboratory aims at a limit for the violation probability of the order of 10 −29 to 10 −30 . The method is based on the search for Pauli-forbidden x-ray transitions in a pure copper conductor using silicon x-ray detectors with high resolution in energy. The experimental setup, results obtained so far and new ideas to further enhance the sensitivity will be presented.

High sensitivity test of the Pauli exclusion principle

Johann Marton, M. Cargnelli, Tomoichi Ishiwatari +2 more

Full text: The Pauli Exclusion Principle (PEP) represents one of the fundamental principles of modern physics and much of our comprehension of the matter is based on it. There are no compelling reasons to doubt its validity, but a lively debate on its limits is going on, due to the lack of an explanation based on fundamental principles. One possible experiment is to measure the violation of PEP with electrons. The experimental method consists of introducing new electrons into a copper strip and to look for x-rays resulting from the 2p {yields} 1s anomalous x-rays transitions emitted if one of the new electrons would be captured by a copper atom and cascades down to the 1s state already filled with two electrons of opposite spin. The goal of the VIP experiment is to lower the present limit on the probability that PEP is violated by electrons, obtained by Ramberg and Snow (limit {<=} 1.7 x 10{sup -26}) by about 4 orders of magnitude. To minimize the background the measurement will be performed in the Gran Sasso underground laboratory. Preliminary measurements were already performed. Presently the experiment is collecting data in Gran Sasso. The limit of PEP violation was already improved by two orders of magnitude. The results will be presented and the physics case discussed.
