  A light front treatment of the nuclear wave function is developed and
applied, using the mean field approximation, to infinite nuclear matter. The
nuclear mesons are shown to carry about a third of the nuclear plus momentum;
but their momentum distribution has support only at for vanishingly small
values of the plus momentum, so the mesons do not contribute to nuclear deep
inelastic scattering. This zero mode effect occurs because the meson fields are
independent of space-time position.
