On the Pauli principle violation in QFT

Abstract

We propose a new mechanism for a ''small" violation of Pauli Principle in the framework of Quantum Field Theory. Instead of modification of algebra - commutation relations for fields - we introduce spontaneous violation of Pauli Principle which is proportional to the vacuum fermionic condensate.
