Neutrino, wine and fraudulent business practices

Abstract

The search for the neutrino and its properties, to find if it is a Dirac or Majorana particle, has kept physicists and engineers busy for a long time. The Neutrino Ettore Majorana Observatory (NEMO) experiment and its latest demonstrator, SuperNEMO, demanded the development of high-purity low-background $\gamma$-ray detectors to select radioactive-free components for the demonstrator. A spin-off of these detectors is inter-disciplinary measurements, and it led to the establishment of a reference curve to date wines. In turn, this proved to be an effective method to fight against wine counterfeiters
