Abstract

We propose a novel solution to the measurement problem based on quantum field theory and Haag's theorem. According to our proposal in elementary interactions where the particles content is changed, the temporal evolution is non unitary. These interactions which are almost instantaneous lead to a genuine stochastic selection of an outcome subspace that has a distinct particles content but can be a superposition of momentum states, spin states, etc.
