Quantum states with space-like energy-momentum

High Energy Physics - Theory 2009-11-10 v2

Abstract

A common assumption in quantum field theory is that the energy-momentum 4-vector of any quantum state must be time-like. It will be proven that this is not the case for a Dirac-Maxwell field. In this case quantum states can be shown to exist whose energy-momentum is space-like.
