Dark Energy in an Axion Model with Explicit Z(N) Symmetry Breaking

Abstract

We point out that a well known axion model with an explicit Z(N) symmetry breaking term predicts both dark energy and cold dark matter. We estimate the parameters of this model which fit the observed densities of the dark components of the universe. We find that the parameters do not conflict with any observations.
