  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,
p+; but their momentum distribution has support only at p+ =0, and 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.
