We present a model which contains a new complex scalar field Ψ, interacting with a new real
scalar field,
χ, and an effective potential whose symmetry is almost exact, being explicitly broken
by Planck-scale effects. We study the possibility of relatin
g inflation with the dark matter of the
universe. We find that for exponentially small explicit breaking, the model accounts for a period
of inflation in the early universe and gives a dark matter candidate particle.
