    "abstract": "The Pauli exclusion principle (PEP) represents one of the basic principles of\nmodern physics and, even if there are no compelling reasons to doubt its\nvalidity, it still spurs a lively debate, because an intuitive, elementary\nexplanation is still missing, and because of its unique stand among the basic\nsymmetries of physics. A new limit on the probability that PEP is violated by\nelectrons was estabilished by the VIP (VIolation of the Pauli exclusion\nprinciple) Collaboration, using the method of searching for PEP forbidden\natomic transitions in copper. The preliminary value, ${1/2}\\beta^{2} \\textless\n4.5\\times 10^{-28}$, represents an improvement of about two orders of magnitude\nof the previous limit. The goal of VIP is to push this limit at the level of\n$10^{-30}$.",
