Spontaneous Symmetry Breaking without *P*^{+} Zero Modes

### Abstract

The nonrelativistic interpretation of quantum field theory achieved
by quantization in an infinite momentum frame is spoiled by the inclusion
of a mode of the field carrying *p*^{+}=0. I shall describe
work with Joel Rozowsky in which we explore the viability of doing 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 physics of SSB
in scalar quantum field theory in 1+1 space-time dimensions is accurately
described without a zero-mode.
