  "abstract": "<p>The VIP Collaboration is performing high precision tests of the Pauli&nbsp;Exclusion Principle for electrons in the extremely low cosmic background&nbsp;environment of the Underground Gran Sasso Laboratories of INFN (Italy). The experimental technique consists in introducing a DC current in a copper conductor, searching for K<span class=\"math-tex\">\\(_{\\alpha}\\)</span>&nbsp;PEP-forbidden atomic transitions when the K shell is already occupied by two electrons. VIP set an upper limit on&nbsp;the PEP-violation probability <span class=\"math-tex\">\\(\\frac{1}{2} \\beta^2 &lt; 4.7 \\times 10^{-29}\\)</span>. The aim of the upgraded VIP-2 experiment is to improve this result at least by two orders of magnitude. The improved experimental setup and the results of a preliminary&nbsp;data analysis, corresponding to the the first run of the VIP-2 data taking (2016&ndash;2017), will be presented.</p>",
