Title: Experimental Search for a Violation of the Pauli Exclusion Principle for Electrons: the VIP experiment

Abstract

The Pauli exclusion principle (PEP) is one of the basic principles of modern physics and, even if there are no compelling reasons to doubt its validity, it is still debated today because an intuitive, elementary explanation is still missing, and because of its unique stand among the basic symmetries of physics. A new limit on the probability that PEP is violated by electrons, was established by the VIP (VIolation of the Pauli exclusion principle) Collaboration. The obtained value (1/2){beta}{sup 2} < 4.5 x 10{sup -28} is an improvement of about two orders of magnitude of the previous existing limit.

  • The Pauli Exclusion Principle (PEP) is one of the basic principles of modern physics and, even if there are no compelling reasons to doubt its validity, it is still debated today because an intuitive, elementary explanation is still missing, and because of its unique stand among the basic symmetries of physics. We present an experimental test of the validity of the Pauli Exclusion Principle for electrons based on a straightforward idea put forward a few years ago by Ramberg and Snow (E. Ramberg and G. A. Snow 1990 Phys. Lett. B 238 438). We performed a very accurate search ofmore » X-rays from the Pauli-forbidden atomic transitions of electrons in the already filled 1S shells of copper atoms. Although the experiment has a very simple structure, it poses deep conceptual and interpretational problems. Here we describe the experimental method and recent experimental results interpreted as an upper limit for the probability to violate the Pauli Exclusion Principle. We also present future plans to upgrade the experimental apparatus.« less
  • We present new limits on exotic keV-scale physics based on 478 kg d of MAJORANA DEMONSTRATOR commissioning data. Constraints at the 90% confidence level are derived on bosonic dark matter (DM) and solar axion couplings, Pauli exclusion principle violating (PEPV) decay, and electron decay using monoenergetic peak signal limits above our background. Our most stringent DM constraints are set for 11.8 keV mass particles, limiting gAe < 4.5 × 10-13 for pseudoscalars and ðα0=αÞ < 9.7 × 10-28 for vectors. We also report a 14.4 keV solar axion coupling limit of geff AN × gAe < 3.8 × 10-17, amore » 1 2 β2 < 8.5 × 10-48 limit on the strength of PEPV electron transitions, and a lower limit on the electron lifetime of τe > 1.2 × 1024 yr for e- → invisible.« less
