Abstract
A non-local field theory which breaks discrete symmetries, including C, P, CP, and CPT,
but preserves Lorentz symmetry, is presented. We demonstrate that at one-loop level
the masses for particle and antiparticle remain equal due to Lorentz symmetry only. An
inequality of masses implies breaking of the Lorentz invariance and non-conservation of
the usually conserved charges.
