In calculating this propagator for n noncovariant gauge bosons those non-local terms demand the use of a prescription to ensure causality. We show that from 2 gauge bosons onward the implementation of such a prescription does not remove certain pathologies such as the non existence of two or more free propagating gauge bosons in the light-front form.Prepared for 24rd Brazilian National Meeting on Particle and Fields, Caxambu-MG, Brazil, 2003High Energy Physics - Theorytext
