Local quantum field theory of possible violation of the Pauli principle.

Abstract

We generalize to a local relativistic quantum field theory a proposal of Ignatiev and Kuzmin for a single oscillator which has small violation of the Pauli principle and thus provide a theoretical framework which, for the first time, allows quantitative tests of the Pauli principle. Our theory provides a continuous interpolation between fully hindered parafermi statistics of order 2 ($\ensuremath{\beta}=0$), which is equivalent to Fermi statistics, and ordinary parafermi statistics of order 2 ($\ensuremath{\beta}=1$). We suggest two types of experiments which can place bounds on $\ensuremath{\beta}$.
