Abstract
The nonrelativistic interpretation of quantum field theory achieved by quan tization in an infinite momentum frame is spoiled by the inclusion of a mod e of the field carrying p(+) = 0. We therefore explore the viability of doi ng without such a mode in the context of spontaneous symmetry breaking (SSB ), where its presence would seem to be most needed. We show that the physic s of SSB in scalar quantum field theory in 1 + 1 space-time dimensions is a ccurately described without a zero mode.
