Abstract

Pauli exclusion principle (PEP) violations induced by space-time noncommutativity, a class of universality for several models of quantum gravity, are investigated by the VIP-2 Lead experiment at the Gran Sasso underground National Laboratory of INFN. The VIP-2 Lead experimental bound on the noncommutative space-time scale $Λ$ excludes $θ$ -Poincaré far above the Planck scale for non anishing “electriclike” components of $θ_{μ ν}$ , and up to $6.9 \times 10^{- 2}$ Planck scales if they are null. Therefore, this new bound represents the tightest one so far provided by atomic transitions tests. This result strongly motivates high sensitivity underground x-ray measurements as critical tests of quantum gravity and of the very microscopic space-time structure.
